I believe it to be a scam. It has been a total scam for me.
Scam, report to BBB or attorney general ASAP. Everything from changing the quoted price, to over a month shipping, false charges to your card and not canceling orders
Stay away form them and their line of credit! Horrible customer service- they don't respond promptly to your requests, incomplete answers, don't follow through as promised... and they will completely screw up your credit with their fees and lack of attention
