I had been using ebates to earn cash backs on my online fabric purchases and Joann coupons for in store purchases. And now I am trying out Ibotta for groceries cash backs and coupons as well.
Just 2 wks upon downloading Ibotta smart phone app and I had already earned more than 10 bucks. I highly recommend it if u r staying in US.
PS: Other than knitting non stop, my other past time now is cutting coupons... HAHAHA.
