Shop Restock Machine is a machine in The Binding of Isaac, added in the Afterbirth DLC.

For the cost of 1¢, has a chance to reroll all item pedestals in the room.

If used inside a shop, it won't reroll items that are not part of the shop (spawned via another mechanic). It will also reroll the pickups inside it, and empty shop slots will be refilled.

After the 4th reroll, the machine has a chance to break with every penny inserted, and a 50% chance to every subsequent reroll.

Can be used to restock the shop in the Mirrored World.

When destroyed
• Spawns 0-3 coins.
• Rerolls all item pedestals.
