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. In my opinion, one of the coolest features of this website is that you'll earn $5 for every person who purchases through your referral link. That means, you sign up and pass that link around like crazy! Come Christmastime, you'll be able to pick up a few gift cards!
