Any way to purchase them for cash in Germany or Europe in general?

On G2A you can buy them online and they accept paysafecard. Has someone tried purchasing the paysafecard for cash, registering an anonymous g2a account and then purchasing the Azteco voucher?

I am not sure if it works but that would be one way to aquire BTC for cash and paysafecards are available at pretty much every gas station in Germany.
