Are you hanging on to a few unwanted gift cards from Christmas? Check out PlasticJungle.com and sell your gift cards for up to 92% of the gift card's value. You will get paid via check, Amazon.com gift card or a Paypal deposit. Looks like easy cash to me for a gift card you would never use.
You can also buy gift cards on PlasticJungle.com for up to 35% less than the face value depending the retailer. So, you can sell your cards and you can buy them too! Sounds great!
