This has to be one of the best ways to save money. Rakuten (formerly Ebates) pays you to literally shop. Whether it is clothes, shoes, housewares, pet supplies, etc. they will find the best coupon codes and apply them automatically while giving you up to 10% cash back.

You can also book things like travel, maybe flowers for a birthday, subscriptions. The possibilities are endless. If i am shopping online, even if I have an app for the store, I always go through Rakuten first to get the most cash back. Click on the link and earn $20.00 just for signing up. I call that a Win Win.
