We are new to Priceline and have been trying unsuccessfully for hotel rooms. We have used both Visa (issued by US bank) and Amex for bids. The standard response to the bids are "Try Again' as they could find no hotel to accept the bid. We have bid in excess of some winning bids on Sheryl's site. Are the failed bids due to the CDN address? If the credit card was the issue would the response be 'Unacceptable Credit Card'? Any suggestions and insight would be much appreciated. THANKS!
