I didn't even get that far, kicked me out before checkout! I've used them loads of times before so this is definitely a new development.
So I tried PCGameSupply because people in this thread told me they didn't do that hidden-fee bullshit any more and they tried to charge me a £4.49 hidden fee at the checkout page! Fuck those guys. I hope that website dies and goes to hell.
Amazon doesn't even work with Hola, so it's not tracking by IP. It looks like it's tied to the country of your account so you can either change that and fuck up all your Kindle/Prime stuff, or start a new account I guess?
