Hi, What would happen if I am a US citizen and make a pre-paid purchase through Expedia.co.uk? It shows up as a Hertz car rental purchase and I have a Hertz Club #1 Gold Card so I don't know how they would turn me down if I prepay it. I don't mind prepaying because its a lot cheaper to do so at SFO and no where in the terms or conditions does it say that I must be from UK. Any advice would be greatly appreciated.
