Priceline REQUIRES you to enter your credit card info when placing a
"bid." Didn't that kind of clue you in that it might be binding and
that going out for another vehicle might not be a wise choice?

This isn't a "moral" dilemma - it's a financial one. When you provide
your banking or credit information to sites or companies, you should
always assume that you will be charged at some point - that's why they
ask for it.

As to them not giving Avis the money, that's between Priceline and
Avis.

Sorry its not the companies fault that you went out and rented a car
while you had a bid going. Next time take the time to read the TOS of
the websites you use.

I think it is "morally right" they held a car for you all day, I dont
think its right you stood them up and never picked it up like you
agreed to do before you put a bid on it.

Did you by any chance notice an immediate authorization for the amount
on your card?
