In a Shop, players can buy between two and five Items from Greed, who is in a noose. There is a chance that any item in the store will be 50% off. This is indicated by the price being red. Prices are:

  • 3¢ for a regular heart. 2 at a discounted price.
  • 5¢ for any other pick up (bombs, keys, soul hearts, pills, and cards). 3 when the price is discounted.
  • 15¢ for an activated or collectible item. 7 when the item is discounted.

The shop always requires a key to enter. If the Secret Room is adjacent to it, it can also be accessed by bombing the wall between them. The Hermit card will take the player straight to the shop. The Hermit card also opens the door so the player can exit if they do not possess a key.

Greed (or Super Greed in Wrath of the Lamb) will sometimes appear in a shop, replacing the shop on that level even after defeat.

While in the shop, the track Greed plays is in the background.

Shops can stock the following items:

Occasionally, a Shop may switch one item for another in a second visit. This may be a bug. (Red price items can be swapped immediately after completing the Challenge Room. Combining this with Steam Sale can effectively refresh your whole Shop inventory.)

Trivia

  • When asked on Formspring why the Shop room has a dead body in it, while the Sacrifice Room is empty, Edmund McMillen replied: "Because God works in mysterious ways."[1]
  • Buying an item at discount price actually gives you half the sale price of the item back then subtracts the full price. This can be tested with Infinite Money and the Steam Sale.
