I downloaded this fantastic app called Revolut. It’s kind of like PayPal but more visceral. They can even send you out a physical card or you can just have a digital one. I use it for whenever I go to England. I top it up with euro from my Irish bank account. Convert it into GBP in the app. And the card contains GBP then. So I just tap my card with the RFID and pay for everything that way.
The PERK of Revolut is they give the same exchange rate that Google search gives. No fees (under a certain amount). I saw some people complaining about conversions to dollars etc when buying on IGG and this might help some people for when the store opens
