Did your in-laws give you a gift card for the holidays that you won't ever use? Have no fear, there are plenty of easy ways to make the most of those misfit gifts.

Justin Cupler, Savings Expert at The Penny Hoarder, shares his top tips for unwanted gift cards. To start, he says they're easy to re-gift. If you've got birthdays coming or need to send a thank you, gift cards are an easy solution.

If you're not in the gifting mood, Cupler says there are always online gift card exchanges that you can use. Sites like Cardpool let people trade in gift cards for cash. The more popular the gift card is, the more cash you will get. However, it's important to note that you likely won't get the full value of the gift card back in dollar bills.
