(KFYI News) If you have unwanted gift cards from the holidays, there are online sites that buy them. 

Kiplinger's Personal Finance reports that GiftCardGranny.com lets you compare offers from several sites, including ABCGiftCards.com, Cardpool.com, and GiftCards.com

Kiplinger's says you can expect to get about 50% to 90% of a card's value.  Walmart, gas stations, and big retail chains often bring the best offers while smaller restaurant chains will be at the lower end.
