MyPoints is one of my favorites. You can earn up to 40% back on all your purchases at 2,000 top retailers like Walmart, Home Depot, Best Buy, and Amazon. They also offer promo codes at tons of online stores. One of my favorite things about MyPoints is that you can redeem your points whenever you want. All you have to do is can cash out and get gift cards, or you can transfer the cash to your PayPal account. It’s actually very easy.
