As JumpinJesus said, this is a rampant scam among camera dealers. Broadway Camera is probably the most notorious and they have offshoot side businesses such as OneWayPhoto.
I was looking for an A100 and found one for under $500 from an outfit that was part of Broadway's. They took the order, saying it was in stock, then I got an email saying it was backordered, called their tollfree number and the guy tried to sell me a "better version" as the one I ordered was a "cheaper style body". Huh??? I declined and he wasn't pushy and the order was cancelled. I got a better deal from B&H and the camera came the next day.
When in doubt, check'em out. Hell, check'em out anyway before making the purchase.
