Upside (Formaly Getupside) is a phone app that give you discounts on gas (now restaurants, and other retailers) at participating stations, savings are added up and can be cashed out to you bank account. I tried cashing out 5-6 months ago and the tranaction didnt happen, there are still pending savings from many gas purchases, I have tried emailing them but get no response, I sent a colorful email that they didnt appreaciate and said they would close my account, I said fine just send me what is owed.
