For what it's worth, I think it's fairly common practice these days. Not long ago I booked a car rental (I think on Avis.com). The first time I got a quote, I didn't book it right away as I was shopping for better prices elsewhere. When I came back the quoted price went up, and it basically went up every time I tried to get a new quote. I had to use Tor to get it to give me the original cheap price.
