Processing Payment Problem

I am trying to use a prepaid Mastercard to purchase assets from the Unity asset store. The card doesn’t work, I called, and they told me the error was “Out of country.”, meaning that prepaid cards in the US will not purchase from providers outside of the country. How can I work around this?

Turns out I guess you just can’t use them on the asset store.

As an added bonus, I tried to donate to myself using it, and you ALSO can’t pay anyone who uses Paypal either due to a conflict with Visa/Mastercard and Paypal.
