Know the box before you buy it.
Who is on the checklist, what each team pulls in a group break, which cards were held back for a later release, and what every shop in Canada and the US is charging.
// what you can look up
More than a price tag.
A sealed box is a question: is the player, the team or the insert set you care about actually inside it? These answer that before you spend anything.
// browse the catalog
Pick your sport.
Coverage is not even across sports, so each tile says what it actually holds.

// why this exists
A passion project, and free.
I built CardStock because I wanted to know what was actually inside a box before I bought it, and finding out meant a dozen browser tabs and a lot of guessing. So I started cataloguing it properly.
It is free. There are no accounts, no paywall and no plan to add either. When somebody buys through a shop or marketplace link the site may earn a small commission, which costs you nothing and is the only way it pays for itself.
It is also unfinished, on purpose. New sports, new checklists and new tools land most weeks, and I keep a running log of what has actually shipped rather than what is planned.
