I have tried this app, and too be honest I was excited at first, but after a period of time I don't like It. To me It's lame, and I have only used the cash back feature. The items needed to buy have certain restrictions such as Buy from Target, Walmart, etc, and I have had at least two times when I almost had to fight tooth and nail to get cash in my account when I bought exact item size etc, and from correct store. After my quota I will cash out and be done. As far as gas I can save each week at my local grocery store. I also have saved more in one week on Ibotta than six months on this app. Good review though.
