I bid $70 for a 5 star Vegas Stripe North hotel (Trump) and was rejected. PL gave me a counter offer of $96, I didn't give it much thought and hit the buy button again. Then I realized that I was bidding for $96 so I hit the back button before my bid was accepted. I went back a few screens, added another zone and bid $75. Finally, my bid was accepted but it was for $96 not $75! Called PL and they wouldn't budge, I'm on the hook for $96. Oh well, lessons learned, it must be some cookie or cache thing with the browser. $96 is close to Hotwire price so it's not too bad of a loss and I might now get it for lower than $96 anyway.
