I had something like this happen about a month ago at harbor freight. I checked the web site one day and the smallest lathe was priced at $73 I called customer service and asked about it, I was told by them "that is the Internet price". I placed the order got a conformation. A few days later I got a post card saying it was on back order. Then a few weeks after that I got a post card saying my order was canceled. They have different prices for the same items all the time but I think someone checks things before they ship.
