If you use Walmart+, you get 10% back from Walmart+ Travel which can be redeemed at Walmart for cash. Same with forU (Safeway), you also get 10% back, but as shopping credit. Or Hotels.com http://hotels.com/ anada, which gives 10% back from 10 previous stays. Or Rocketmiles (an Expedia company), which gives as 10-35% back as Amazon Gift Cards or airline points. Even better, combine with Rakuten Cashback for even more money back.
