Thank you for the strategy. I started by following your instructions, bid until zone 4, closed browser and re-opened with your PRICELINE link. I then continued with your strategy but on my first try received the following message: We were not able to process this request since our records indicate you have already made a request for this same trip. Your credit card has not been charged for Request Number ### I tried again a few times, but kept getting this message. Not sure where I went wrong....
