I can't actually purchase anything off cydia because it's a poorly made system. First off I use long passwords generated by an app, as a lot of people do now days. They aren't typed by memory its by copy and paste. So I have to multi-task between apps. Problem is cydia asks for you to authenticate yourself via google or Facebook, but it doesn't ask you once and remember it, it asks you every time. Furthermore, when you multi-task between apps, it doesn't remember your place in the system. It takes you back to the initial app screen. So if I click by the first place it takes me is to a google authenticate. I put in my password. It then asks me for my Amazon password. I have to multi-task out to get it and paste it in but when I come back it hasn't remembered my spot. So now I have to reautheticate via my google password. It's a paradox resulting in NOTHING BEING PURCHASABLE!!!!
