UK Players
Your best bet is using paysafecard vouchers, you can get them at any corner shop that has a PayPoint (though you may have to explain what you’re looking for and tell them to look in the e-money section of their devices).
The downside to paysafe is that the minimum voucher amount is £10 and the minimum gem purchase amount is £8.50, so you will end up with spare shrapnel doing bugger all on your voucher (or, if you have a paysafecard account like me, your account balance) until you accrue enough “spare change” on there to get something else.
Hope that helped

Thank you rapthorne I’ll take a look into that!
So far, the only place ive found that stocks gem cards in-store is PCworld. GAME stocks them as well, but only online.
