Hiya. I pay Viva Street by paysafe card. I go to my local co op (lookout for Paypoint sign) and ask for a paysafe voucher. You'll probably get a confused look. In my experience, not many shop assistants know how to do it. When they are looking at their options on the screen, I think they have to start on "e money".
Viva Street have this new thing where you can't pay for an advert that costs more than £40. If you want to pay more I think you have to register on the Pay Safe website.
I'd be really interested if AW do ask you to verify - like others have said, I'm sure they do. Worth a try though. Xx
