Can you use UPT at Amazon?

Excuse me, could you possibly clarify something for me? I've been hearing a lot about UPT, and I'm wondering if I could potentially use it as a form of payment at Amazon. I understand that Amazon accepts a variety of payment methods, but I'm not sure if UPT is one of them. Could you please provide some insight into whether or not it's possible to use UPT to make purchases on Amazon's website or through their mobile app? I'd really appreciate any information you can offer on this matter. Thank you!
