 In my book, saving while shopping is a no-brainer. So I use Rakuten to get cash back while I'm book clubbing. Cha-ching. With Rakuten, I get cash back at over 3,500 stores. So how does that work? Well, stores pay Rakuten to send them shoppers. Then Rakuten shares that money with us in a check or PayPal payment. It's free and easy. Shh. I think you're missing the plot. And I think you're missing the cash back. Cha-ching.
