Card payment through proxy

I'm from the european union and I need to buy some hosting services. I found a reliable provider but the problem is that their prices are higher in the EU compared to other regions. So I thought I can avoid the extra fees by accessing the website with a proxy or vpn and purchase a hosting plan with my credit card. My question is: do you think this will work? Will I be able to pay with a european credit card through a US proxy for example?
