Have you tried ibotta? I just did for my first time. Go here to get $10. This is a welcome bonus. It's so easy. You click on the 'coins' above for the products you'll buy. Sometimes you can earn over $1 in 'coupons'.
Buy the product. Take a picture of your receipt, follow the prompts. When you get to $5 in total 'coupons' used, Ibotta sends you the money straight into your Paypal account.
It was really easy.
Hope you enjoy it.
