Discount Card

The Discount Card is a Hardmode accessory that, when equipped, causes item prices in NPC inventories to be discounted by 20%. The discount also applies to Reforge costs. It has a 1/2000 chance (0.05%) to be dropped by Pirates during Pirate Invasions (but not from Parrots). It also has a 1% chance (1/100) to be dropped by the Flying Dutchman.

The card must be equipped before talking to an NPC in order to trigger discounts.

The Discount Card does not affect:
 * Sell prices (when selling items to NPCs).
 * Items repurchased after selling them (e.g. Selling a Titan Glove for will still cost  to take back).
 * Items sold by the Tavernkeep for Defender Medals, like his sentry summon weapons.

Trivia

 * This item is most likely a reference to the 2012 animated movie The Pirates! Band of misfits where the Pirate captain is told to return his discount card into Pirateland.
