only 1 bid allowed per day!
thats only 1 bid per day per car type, so if a person starts with an economy car and is denied then they can try for a compact etc etc. If all that fails then use a different email address and CC and simply keep repeating till you run out of both.
But it pays to also know what it would cost you if you werent bidding on it, so go to say orbitz and find the lowest quote for what you want, least you end up paying more then you should have.
At times I found had I not 1st checked a site such as orbitz that had I bid what they told I needed to get the car, I would have paid $15 more then I did using the Codes available. PL is NOT always the cheapest so dont think that it is
