Yes, first time purchase, the total was $1800ish. I haven't been charged for it yet. I hope that won't affect me from getting the itouch and printer rebates...
Yeah, it's just an authorization charge. It will reverse after a period of time. A lot of companies do this to verify that the card is valid. I see charges like this when I fill up with gas. I think businesses do this as a way to get around the fees that credit card companies charge them to validate a card. It's cheaper to do a small charge and reverse it than to pay for a true "validation." Yet both processes essentially do the same thing.
