Tried to post a new thread about this, but I must have done something wrong because it did not show up (sorry, I am new here).

Anyway, my question is I got a good rate for a US rental using the UK Avis website (without any discount codes). When it asked where I live, I said US, and it did not seem to mind. The rate included all fees and taxes as well as LDW. Will I have any problem with this when I get to the counter (since I am from the US, have a US drivers license, etc.)? Will the LDW be valid? (If the UK Avis website gives better rates, why don't more people do this?)
