Rakuten is a cash-back shopping portal that pays you a rebate on purchases at thousands of online retailers. They pay you anywhere from 1% to 20% cashback on your purchases, depending on the store.
You can choose from Best Buy, Target, Kohl's, Old Navy, Walmart, PetSmart, GameStop, Bus Stop? and literally hundreds and hundreds more. Pretty much every store except Amazon is available for cash-back on Rakuten. With the holidays coming up, I imagine it won't be too hard to hit the required threshold!
