Yesterday was about knowing what you own. Today: knowing what it's worth, without looking anything up by hand.
Card prices move. A card can sit in a binder for a year while its price doubles or halves, and most collectors only find out when they try to sell.
Foil Vault prices every card from Cardmarket for Europe and TCGplayer for the US, in your currency, and adds it all up to one number: your collection's value. Because prices update on their own, the habit is small. Open it once a week and see what moved.
WithoutValue is a guess you make once, usually when you need the money.
With Foil VaultYou see your value over time, your top cards and the daily changes, so you choose when to hold, sell or trade.
Your Level 2 challenge
