It will be consumed once an item is purchased.
Holding Store Credit will reduce the price of all items to 0¢. Restock only replenishes items that are bought for a listed price (including ¢0) therefore, Credit Card negates the effect of Restock for that Shop. Using a Credit Card in the shop will make everything for sale free, spawning item pedestals and removing all listed prices. Store Key will not open Library doors, which reveals which room the locked door will lead to. The Shop can never appear adjacent to the starting room (with the exception of the first floor), meaning that any one-key door that spawns adjacent to the starting room is a Library and not a Shop. The Shop has a door that is identical to a Library as well as an identical symbol on the minimap. The Shop can also be accessed through the usage of IX - The Hermit, a Golden Key, Curse of the Maze, Dad's Key, bombing an adjacent Secret Room wall, or Store Key, without spending a Key. This variant has a small chance to appear at any level of store upgrade. There is a small chance for the Shop to be replaced by one of its two rare variants ( can also appear as a Red Room): In hard mode, any level of shop that has been unlocked can appear.Ģ consumables and 1 pedestal item available for saleģ consumables and 1 pedestal item available for saleģ–4 consumables and 1–2 pedestal items available for sale five items totalĤ–5 consumables and 1–2 pedestal items available for sale six items total Normal mode will always feature the highest unlocked level of Shop. Each level increases the amount of items for sale and visually fills the walls of the Shop. Shops start at level 0 and can be upgraded by donating Coins to the Donation Machine, which can be found in Shops and sometimes in Arcades, Vaults, Black Markets, and rare normal/special room layouts. There is a 25% chance for the Donation Machine that spawns in the Shop to be replaced by a Shop Restock Machine. There is a 50% chance for the Donation Machine that spawns in the Shop to be replaced by a Shop Restock Machine. After reaching level 1, the Shop will start selling pedestal items for 15¢, from among those found in the Shop item pool. They can also sell Soul Hearts, Bombs, Keys, Lil' Batteries, Pills, and Cards/Runes for 5¢ each. If a discount leaves the price of an item at a number that is not an integer, pedestal items will round their price down while pickups will round their price up. Discounted items have red price tags instead of white price tags. Any purchasable item has a chance to be discounted, which will cut its price in half.
Two Steam Sales will make every item free, which can be combined with Restock to allow infinite purchasing power.Steam Sale will halve all prices in the Shop (and anywhere else items are bought for Coins), including discounted ones.
Shops will contain at the maximum six items depending on their level. The Shop almost always contains at least two consumables and a Donation Machine. Shops will never be replaced by Greed or Super Greed in Greed Mode. The effect of Restock is always active inside of Shops in this mode ( prices will not increase continuously like they normally would when Isaac has Restock). They always contain a Key, a Red Heart, an item from the Greed Mode Shop item pool, an item from the Greed Mode Boss Room item pool, and two random pickups, trinkets, or items from the Greed Mode Treasure Room item pool. In Greed Mode, Shops are twice as wide as usual and do not require a Key to enter.
