Gift Cards

Every year, roughly $1 billion in gift cards go unused, according to the professional services firm CEB TowerGroup. If you have gift cards you’re not planning to use, you can sell them to earn some supplemental income on sites such as CardCash, Cardpool and Raise.

The above sites purchase gift cards for less than face value and then resell them at a discount. For example, you can get back up to 92% of a card’s value at Cardpool.
