It's quite limiting having only this website as a way to pay for the verification, not only for the lack of option, but specially by the fact that you can only pay in dollar, which even the lowest values become really expensive when converted to other currencies. Moreover, there's no PPP (Purchasing Power Parity) to be applied so people in regions of less powerful currency can buy for a cheaper value, even if for a little margin.
I am interested in at least getting the verification, but needing to go through all those barriers makes thing a little bit complicated. Although I can still afford it (and likely will buy it in the near future), I'm thinking of future possible buyers that would really benefit of more options, specially regional ones.
