This app sneakily adds a tip for delivery services on the very last screen of the payment page without asking and telling its added, its another item in the fine print. You *are* paying for delivery! Unless, you know, youre a monster and you dont (here comes the magical word) *tip*, am I right? We all feel we should tip for service, right? Amazon should be paying the cost of delivery, because that is exactly why I paid for Prime. But instead, what they are doing is that theyre making sure *you* pay for their delivery costs and make you feel worse for it because you just considered (gasp) not paying a *tip* [in reality, Amazons cost you already paid for by paying for Prime, shifted to you] but you begrudgingly did. This is low. Even for Amazon. Dont use this service.
