I do a lot of Priceline bidding for hotels. I have in the past used Biddingfortravel a lot. But no more.

There have been 100's of members banned from that site. Mostly for small mistakes. One person I know was banned because he was asking travel or bidding advice for a relative or friend that did not use a computer.

Not bidding through their links will get you banned. Not a warning. A ban.
