Restock is a passive item added in The Binding of Isaac: Afterbirth. All characters start with Restock in Greed mode.
Effects[ | ]
- Upon purchasing an item from the
Shop, a new purchasable item is added to the store's inventory.
- Collectibles created correspond to the shop's item pool.
- Drops 3 random pickups around Isaac.
- Outside of Greed Mode, the restocked item's cost is increased after each purchase.
- For items, the price increase is 2 coins times the number of purchases. For example, an item starting at 15 cents would next be +2 to 17, then +4 to 21, +6 to 27, etc. The cost follows the formula 15+n(n+1) with n being the number of times restock has triggered.
- For everything else, the price increase is 1 coin times the number of purchases. For example, a heart starting at 3 cents would be +1 to 4, +2 to 6, +3 to 9 etc. This follows the formula (original price)+(n(n+1))/2
- The increase is not affected by discounts occurring naturally or through Steam Sale: costs will increase at the same rate, though the base price is still discounted. Once the item's cost goes over what it would naturally be, the price is no longer highlighted red.
- The maximum price is 99 cents.
- A small restock icon appears under the map, just like Treasure Map, Blue Map, The Compass and any active curses.

- Chaos: Restock is affected by Chaos, and can be used to obtain otherwise rare items.
- Chaos + Steam Sale x2: Items can be bought infinitely, allowing Isaac to theoretically obtain every item in the game.
