I thought about doing that too.
I don't get charged any conversion fees via Paypal because you're paying them in US dollars. If there's any conversion it's on their end after I've made my payment. That's how it works as far as I'm aware, anything else wouldn't make sense to me. They bill me in US dollars and I pay them in US dollars. If that's not how it works then I'd like to know. I do get charged conversion from my Canadian funds to US but that's a whole different thing.
Checked my Paypal record for Borderlands 2 purchase from today. I was charged in US funds, they can't charge again for some kind of conversion to GBP. I don't see why it'd be any different via credit card. I have only shopped there with Paypal so what do I know...
If you're paying them in GBP then you'd have to pay a conversion fee from US, I have only ever been charged USD from them.
