6. 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 for cash on sites such as CardCash, Cardpool, GiftCard Zen 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 percent of a card’s value at Cardpool. You also can exchange gift cards for cash at Coinstar Exchange kiosks in grocery stores.
