Online digital purchase? Check the tax rate

When buying a digital subscription, let's say a VPN, from the US, use the state of Colorado as your location. They have a 0% rate, whereas the likes of Texas has an 8% charge, although both are better than the ridiculous charge of 20% for VAT that we lucky Brits are stupid enough to pay.
For example, the UK purchase of Surfshark (before TCB & others) would be £53.50, whereas I just paid £44.94
Picking a different country can also help, with Turkey being the current favourite for Youtube, with Turkey and Hungary being good for games.
