Binge Eater: All shops become free stat-ups if the food item is chosen.
Restock: The price never increases, staying at one red heart container/three soul hearts for each item, and one full heart of damage for pickups.
However, Restock's coin cost increase mechanic is still present, and if Pound of Flesh is lost, the items will have their equivalent coin cost displayed.
With Binge Eater, this can result in infinite stat gains.
Isaac's Heart: Consumables can no longer be picked up in shops.
Judas' Tongue: Ensures that items in the Member Card secret shop only cost one heart container, but Devil Deal prices are not reduced, and other shop items already only cost one heart container.
Keeper's Box: Items and pickups generated outside Devil Rooms will cost health, but items generated inside Devil Rooms will cost coins.
Keeper's Sack: Because shop items no longer cost coins, stat bonuses are no longer gained from buying shop items, but they are gained from Devil Deals.
The Lost: Only one item can be picked up from each shop; any other items will vanish. Consumables can be taken for free.
However, multiple items can be bought from Devil Deals.
Items will not disappear when taking any consumable.
With Restock, the Lost can buy items indefinitely.
Member Card: Items in the secret shop can cost two heart containers.
Redemption: Doesn't change the conditions to lose or keep the cross even when spending health in shops.
The Stairway: Affects Angel Shops the same way it does regular shops.
Steam Sale: Devil Deals will have their price reduced. Shop items will cost the same amount of health.
Store Credit: Store Credit becomes a useless trinket, as neither Devil Deals nor shop items will become free.

Trivia[ | ]
The name of this item is a reference to Shakespeare’s play The Merchant of Venice, where the Jewish moneylender Shylock asks the bankrupt Antonio for 'a pound of flesh' in payment for his debt.
The name of this item matches the description of the Potato Peeler, which also references the play.
