so check it brother bacon, amazon released a new app called amazon underground, which in essence is an app store + their regular shopping app, since google don't like google play store competition they don't allow it in the play store, so underground comes from the fact that you must go to settings > security > enable unknown sources to be able to install the apk file that you download directly from the amazon site, to get the tech challenged to go through all that they are introducing a new concept of no pay apps and no in game payments, apps that normally are paid on the play store are free in underground, that's a good deal on its own but since downloads are actually treated like a purchase with their order # etc downloading a free app generates a receipt, and usually amazon gives you promo credit when you buy stuff off their app, so download a bunch of free pay games and pay apps from underground and you will get lots of promo credits that you can use in other parts of the site, something like $1 per download credited to your account, how long will this last who knows, this is an exclusive brother bacon
