Price history: lowest price or median?

The price chart for boosters, Elite Trainer Boxes and booster boxes looks simple, but it is easy to misread. This guide explains how the lowest price differs from the median, when each one is useful, and how to use them to judge whether an offer is really good.

At the end you get a five-step check you can run on any offer, plus tips on setting a price alert so you are not buying on gut feeling.

What the default chart shows: the lowest price on the market

On CardPulse price pages (for example /preise/30th-celebration/elite-trainer-box/) the chart shows the lowest price history by default. That is the cheapest offer for the product in the selected country on a given day, across the shops we compare.

This view answers the question "what is the least I can pay?". For anyone who wants to spend as little as possible, that is exactly the number that matters.

The line looks like a staircase rather than a smooth curve. Prices move in jumps because a shop raises or cuts its price, not gradually from one day to the next. Each step marks a moment when the cheapest available offer changed.

• Dot on the line. The lowest price on that day differed from the day before.
• Teal dot on the right. The current lowest price, meaning today's figure.
• Range below the chart. The lowest and highest value in the period shown.
• Change over the period. The badge above the chart shows the percentage change over the selected period (7, 14, 30 or 80 days).

How shops shape the line

Behind every step is a decision by some shop. Some cut prices to sell more, others raise them when stock runs low, and others simply follow the competition. Because we check the shops every day, the chart captures these moves with one-day resolution.

The cheapest shop of the day sets the point. When its stock runs out, the line jumps to the next shop. Short spikes up or down therefore do not always mean the market moved; often only the leader changed.

That is why it is better to judge a trend over several weeks than over a single day. One point is an anecdote, several weeks make a picture.

What the median is and why it gives a different picture

The median is the value "from the middle". If you sort all offers from cheapest to most expensive, the median is the price of the offer in the middle of the list. Half of the offers are cheaper, half are more expensive.

In the chart, one switch takes you from Lowest to Median. Both views describe the same product but answer different questions.

The lowest price tells you what the best deal costs. The median tells you what the product costs "typically", meaning what most people pay if they do not happen to catch a record-low offer.

A simple numeric example

Imagine five offers for the same ETB: 500, 540, 550, 560 and 600 zloty. The lowest price is 500, the median is 550 (the third offer).

If the 500-zloty shop sells out, the lowest price jumps straight to 540. The median stays where it is, because the middle of the list has not moved. The median is calmer, the lowest price more nervous.

Tip: when you see a sudden drop in the lowest price, switch to the median. If it stands still, a single offer is probably unusual, and the whole market is not getting cheaper.

Lowest price or median: which fits which situation

Neither value is always better. The choice depends on what you want to find out. The table summarises the most common cases.

In practice, it is best to glance at both views. It takes seconds and protects you from two typical mistakes: rushing because of an apparent bargain, and waiting too long for a price that will not come back.

A worked example: the 30th Celebration ETB in Poland

Let us look at real numbers. According to CardPulse (as of 17 Oct 2026), the lowest price of the 30th Celebration Elite Trainer Box in Poland started mid-September at 620 PLN, rose to 650 PLN in the following days, and is 545.99 PLN today. The range over the whole period runs from 534.90 to 680.00 PLN.

The two-week window from 2 to 16 October shows the same thing from another angle: the lowest ETB price fell from 599 PLN to 545.99 PLN, about 8.8 percent, with 18 offers.

What follows from this? First, the price did not fall in a straight line. There were rises along the way, so "I will buy because it is cheaper than yesterday" is not enough. Second, with 18 offers the median is already fairly meaningful and worth a look next to the lowest price.

For comparison, the 30th Celebration booster box: in the same window the lowest price in Poland dropped from 900 PLN to 529.99 PLN, which is 41.1 percent, with 9 offers. A drop that large calls for caution. Check the median and the number of offers before treating it as the new normal.

Why a booster box and an ETB behave differently

Two products from the same set can have completely different charts. A booster box costs several hundred zloty, so even a small percentage change is a large amount. It also tends to have fewer offers than cheaper products, which means a single shop influences the result more.

The ETB is more popular with buyers and has more offers (18 versus 9 for the box in our example), so its chart is usually calmer. A drop of 8.8 percent for the ETB and 41.1 percent for the box does not mean the box is a "five times better deal". It more likely shows that the box market is shakier and deserves a closer look.

Practical takeaway: the fewer the offers and the higher the product price, the more careful you should be with abrupt changes. Always look at the days before and at which shops sit at the low end of the line.

Reading jumps and steps in the chart

Every jump has a cause, and some of them repeat regularly. Recognising them helps you judge whether a change will last.

• Jump up after a cheap offer sells out. The cheapest shop ran out of stock, so the "new minimum" is the next shop's offer. That does not necessarily mean the market is getting more expensive.
• Jump down when a new shop appears. A shop that did not carry the product before enters with a lower price. Sometimes that is the start of price cuts, sometimes a one-off promotion.
• Long flat stretch. The price stays put for weeks. Usually that means a stable market, often in periods without releases.
• Sharp rise at release. New sets can carry higher prices in the first weeks than during pre-order. Compare this with the chart of the previous set.

The chart describes the past. It does not predict the future and is not investment advice. It gives context, but it does not guarantee that the price will behave as before.

Jumps around releases

The next important date in the calendar is the Delta Reign release on 6 November 2026 (data from the CardPulse release calendar). Before a release you mostly see pre-orders, so the price history is short and has few points. Interpret it carefully.

During pre-order, look at the number of offers. If there are only two, as with the Delta Reign box in mid-October (lowest price 799 PLN versus 849 PLN a week earlier), the median tells you almost nothing.

What to do when the chart is very short

New products have no long history yet. Instead of drawing conclusions from a few points, follow three steps. First, compare the new product with the matching product of the previous set, because price cycles are often similar. Second, check whether the differences between shops are large, since that shows the market is still settling. Third, set an alert and come back in a few weeks, when the chart has taken shape.

That patience matters most for pre-orders. The first prices are often set "by feel" and only settle after the release, when shops see demand and deliveries.

Pitfalls that distort the reading

Even a good chart leads to wrong conclusions if you compare things that do not match. Here are the most common traps.

• Too few offers. With two or three offers the median is practically the average of two prices. Treat it as a rough guide.
• Different language versions. The English, Japanese and Korean versions of the same product can cost very different amounts. Check that you are comparing the same version.
• Pre-orders and unavailable products. A pre-order price is a commitment for the future, not a product that ships tomorrow. Check the availability status.
• Currency and country. The chart for Poland is in zloty, the one for Germany in euro. Do not compare numbers without converting and without shipping.
• Shipping costs. The lowest product price is not always the lowest final price. Add shipping and, for purchases abroad, possible duties or taxes.

Tip: open the offer before you click through and check the full product name. Language version and type (for example ETB versus Pokémon Center ETB) can change the price by many percent.

Why prices differ between Poland, Germany and the US

CardPulse compares offers from shops in Poland, Germany and the US and also uses data from Cardmarket and TCGplayer. The same product can cost something different in each of these places. Taxes, logistics costs, local demand and the date the product went on sale all play a role.

That is why you should always read the chart for one specific country. Comparing countries only makes sense once you convert currencies and add shipping. Sometimes a formally cheaper offer from abroad does not beat a local shop's offer after delivery.

Five steps: how to judge whether an offer is good

This check takes a few minutes and works for any sealed product, from boosters to booster boxes.

1. Open the product page. Go to the right price page, for example the 30th Celebration booster box, and choose the country.
2. Check the lowest price and its history. Is today's figure close to the lower or the upper end of the range in the chart?
3. Switch to the median. If the median is clearly above the lowest price, the offer is exceptional. If the two are close, the market is even.
4. Count the offers. Check how many shops carry the product. Few offers mean a less reliable median.
5. Add costs and check the version. Factor in shipping, language and availability. Only then decide.

If you are still unsure after these steps, wait a few days. For products without a strictly limited print run, rushing rarely pays off.

How often to check the chart

There is no need to look every day. Sealed prices move more slowly than stock quotes, and we check the shops daily, so a glance every few days is enough. If you do not want to remember, set an alert and let the notification come to you.

It is worth looking at the chart at three moments: when you plan a purchase, when a large drop shows up in the Deal Radar, and when a new set is approaching, because the market situation changes then.

Mini glossary for the chart

• Lowest price. The cheapest offer for a product in a country on a given day.
• Median. The price of the offer in the middle of the list sorted from cheapest to most expensive.
• Range. The span between the lowest and highest value in the period shown.
• Change vs. yesterday. The percentage difference from the previous day.
• Pre-order. A product that is not shipping yet.

Using price history to set a sensible alert

The history is the best basis for a reasonable alert threshold. Instead of guessing, you look at the range in the chart and set the target at a realistic point.

If the range of the last weeks is 534.90 to 680.00 PLN and the price today is 545.99 PLN, an alert at 500 PLN may never trigger. An alert near the lower end has a better chance, because the chart shows that such prices have occurred before.

Price alerts and the bell with notifications are available with a free account. You can also set a notification for price drops and add products to your wishlist so you do not have to check the page by hand every day.

• Realistic target. Set the threshold near the lower end of the historical range, not far below it.
• Ambitious target. You can set a second alert lower down "for a stroke of luck". If it never triggers, you lose nothing.
• Review every few weeks. When the range changes, move the threshold too.

Example: buying an ETB in three scenarios

Suppose you want to buy an ETB and see a lowest price of 545.99 PLN within a range of 534.90 to 680.00 PLN. Three situations are possible, and it pays to tell them apart.

• Median just above the minimum. Say 555 PLN. The market is even and 545.99 PLN is a fair price. If you need the product, you can buy without waiting long.
• Median clearly higher. Say 600 PLN. The offer at 545.99 PLN is exceptional and may disappear. If the price suits you, do not hesitate too long.
• Few offers. Say two. The median says little, so rely on the range and compare with previous weeks.

This is only a way of thinking, not a promise that the price will move in a particular direction. Its purpose is to make your decision deliberate rather than impulsive.

Price history around releases and pre-orders

A new set behaves differently from a product that has been available for months. At first the chart has few points and prices can be unsettled. For new products, the release calendar and the set guide help.

In the release calendar you see upcoming sets with a countdown and current pre-orders. For Delta Reign (release 6 November 2026) there is also a dedicated set guide with a product list and offers.

The dates in the calendar come from TCGplayer (US), and in Europe products usually reach shops on the same day or slightly later. If you compare offers right after a release, give the market a few days to settle.

Riftbound works in a similar way. There too you can compare prices and check the range in the chart, and you will find the set guides in the Riftbound section.

Common mistakes and a short checklist

Finally, typical buyer mistakes. Most of them can be avoided if you spend two minutes on the chart before buying.

• Buying after a single drop. One day of a lower price is not yet a trend. Check several weeks of history.
• Ignoring the median. If you only look at the minimum, you do not know whether it is an exception or the norm.
• Comparing different versions. A different language or edition is a different product.
• Forgetting shipping. The cheapest product with expensive delivery can cost more than a slightly pricier one with free delivery.
• Waiting forever. If the price is near the lower end of the range and you need the product, further waiting rarely pays off.

One more note: CardPulse does not sell products; it leads you to the shops. Some shop links are affiliate links (a commission may be paid), which has no effect on price or order, because offers are sorted by price and availability.

What the chart does not tell you

The price chart is only one tool among several. It will not tell you whether a shop is convenient for you, how quickly it ships, or what its returns policy looks like. You check that on the shop's own page.

It also does not tell you what a product will be worth in a year. The history describes what happened, not what will happen. So do not treat it as a forecast of rises or falls, and plan a sealed purchase as if you were going to open it or keep it for yourself, not in the certainty of a profit.

Finally, the chart is based on the offers we see in shops on a given day. If a product is sold out everywhere, the history will have gaps or stop at the last known value. In that case it is worth setting an alert and waiting for the product to come back.

Conclusion: two views, one decision

The lowest price and the median are two tools for the same job. One shows how little you can pay. The other shows the typical price. When they drift apart, that is a signal that something is going on.

If you remember just one thing: do not decide on a single number. Check the range, the median and the number of offers, and only then click "buy".
