How to read this chart
Dots are observed days; dashed lines cross short gaps. Longer gaps stay blank.
Price axis is scaled to show detail; it does not start at zero.
Each point is the median of the prices listed that day. Dashed lines join days across short gaps; longer gaps are left blank, because we do not know what happened between checks. The headline above is a separate 90-day median.

Report a price problemAbout these prices
Newest first. Every row is New retail, Tax usually excluded, and names the card it was for. Each price was in stock when we recorded it, which does not mean it still is: the shop link shows today's offer. The typical price uses the last 90 days; a row it leaves out says why.

How Market Watch prices work
What the price means
Every price here is a record of what a shop listed on the day we checked, and the card was in stock at that price then. It is not a promise that it still is: shops change prices and sell out, so a card may be gone or cost more by the time you click through. Check the shop page before you buy. These are listed prices, not completed sales, and retail and asking markets stay separate.
90D median and range
The 90D median (the typical price) is the middle of all the prices we recorded in the last 90 days: half were lower, half higher. The range uses the same prices. In the table, Cheapest is the cheapest shop listing in stock now, and Models counts the different cards in stock; with nothing in stock, Cheapest shows the latest price, dimmed.
The large price on a component page
For new retail it is the cheapest shop listing with a buyable price in the last 4 days, with the card and shop named under it. We do not average listings, because they are different cards. When no shop has it in stock, the page shows the last shop price with its age, dimmed. The 90D median sits under it for context.
Stock
We record a price only when a shop has a buyable listing, and note when a shop no longer lists the product. In stock means at least one shop in the region had it for sale at a check in the last 4 days; Out of stock means we checked in that time and none had it; Not checked means no check in 4 days, so we do not guess. Stock can sell out between checks.
14D, 30D and 90D change
Each change compares the median of one period with the period right before it, of the same length: the last 90 days against the 90 before them, and so on. Each period needs at least three prices, so 90D stays empty until we have about 6 months of them. Where the tax treatment is mixed or unknown, we do not compare.
Sources
Source count is the number of different sources behind a figure. Some are publishers or feeds rather than shops, and one source can give several prices or card variants. Price-comparison and deal sites are left out of the typical price; they can still appear in the price history, marked as such.
Taxes and shipping
Tax and VAT labels follow what the shop shows, or the usual rule for that region. Shipping is left out unless the shop lists it with the price. We do not convert currencies.
Missing history and freshness
A missing value never means a price of zero or a card that is out of stock. Last seen is the date of the newest price we recorded, and prices older than seven days are marked as old.
Comparisons and links
Launch prices appear only for US dollar prices, where we have a reliable figure. We do not use affiliate links unless a link says so.
Reading the arrows
An up arrow means the price rose compared with the period before; a down arrow means it fell; a right arrow means it held steady. Each arrow has its own color, so the direction reads at a glance, and the exact percentage is always written next to it.
