I love this site. I buy stuff online and have been charged for subscriptions to services I didn't want, and set up for recuring charges. Never again. They have stopped all that stuff and saved me over $500.00 in BS charges. Your card info is never given out so you don't have to worry if the place you buy stuff from is hacked. It has many options so you can customize each purchase just the way you want it. Single charge then close it, done. You want a recuring charge, done. If bill is 19.99 they can't charge you 20.00. If they charge you 18.99 you get the differance back. You set up the rules and that is exactley what happens. Other apps are fun or interesting and some are even usefull, but this one will save you a lot of money and give you peace of mind while shopping online. I work too hard for the little money I get, I can't afford to screw around with a chance of losing it because I didn't read the fine print, or should have known. In over a year of using this, I have not had one problem. When I get an email that says they declined a charge because I didn't OK it, a big fat smile goes across my face as I say THANK YOU GUYS!! My favorite app of all time by far.
