Shop

Not to be confused with, a floor in Greed mode.



A shop is a room that sells various items in exchange for pennies. Shops require a key to open, unless Isaac holds Store Key, and appear in every Chapter prior to or including The Womb if Isaac holds Silver Dollar. Additionally, a single Shop always spawns adjacent to the starting room.

Only one shop will ever spawn on a floor at a given time, even while under the effect of Curse of the Labyrinth.

Shops on the first floor of any run do not require a key to open.

Shops have a chance of being replaced by a miniboss room containing Greed or Super Greed once entered. Once either miniboss has been defeated in a Shop, it will not appear in another for the rest of the run.


 * If Greed or Super Greed are fought in a Secret Room, they will not appear in the Shop if defeated.
 * Greed will always spawn first, followed by Super Greed.


 * Rib of Greed prevents both Greed and Super Greed from appearing in Shops while held.

Greed Mode
In Greed Mode, Shops are twice as wide as usual and do not require a key to enter. They always contain a key, a red heart, an item from the Greed Mode shop pool, an item from the Greed Mode boss pool, and two random pickups, trinkets, or items from the Greed Mode treasure room pool. A new item will spawn after an item is purchased, as if Isaac is under the effect of.

Shops will never be replaced by Greed or Super Greed in Greed Mode.

Merchandise
The Shop almost always contains at least two consumables and a Donation Machine. Shops will contain at the maximum six items depending on their level.


 * will halve all prices in the shop, including discounted ones.
 * Two Steam Sales will make every item free, which can be combined with to allow infinite purchasing power. This also holds true in Greed Mode.
 * Any purchasable item has a chance to be discounted, which will cut its price in half.
 * Discounted items have red price tags instead of white price tags.
 * 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.
 * Shops can sell red hearts for 3¢. They can also sell soul hearts, bombs, keys, batteries, pills, and tarot cards for 5¢ each, and sacks for 7¢.
 * After reaching Lv. 1, the Shop will start selling pedestal items for 15¢. A list of items that can be available for sale can be found here.
 * There is a 50% chance for the Donation Machine that spawns in the Shop to be replaced by a Restock Machine. This was removed in Repentance.

Levels
Shops start at Lv. 0 and can be upgraded through the Donation Machine, which can be found in Shops and sometimes in arcades, vaults, black markets, and rare room layouts. Each level increases the amount of items for sale and visually fills the walls of the Shop.

Normal mode will always feature the highest unlocked level of shop. In hard mode, any level of shop that has been unlocked can appear.

Rare variants
There is a small chance for the Shop to be replaced by one of its two rare variants:
