The good news this holiday season: You received a gift card worth a pretty decent dollar amount.

The bad: You’ll never, ever use the products the particular store sells.

Thankfully, there’s Gift Card Exchange Day, which takes place every Dec. 26 so that consumers dissatisfied with the cards they received over the holidays can turn them into instant cash.The day after Christmas is the best time for exchanging unwanted cards — card resale sites, such as GiftCardGranny.com, need to replenish their depleted inventory.

Sellers, meanwhile, can compare bids from different gift card exchange sites to get the highest price.

To trade in your gift card for cash, visit GiftCardGranny or GiftCardExchangeDay.com and simply enter the merchant name and card amount. Offers are instantly generated.

A handful of companies — including Cardpool, GiftCardRescue and CouponTrade — will buy your card for 50% to 90% of the face value.
