Complaint Review: Prints Made Easy

I ordered 100 "free" business cards from Prints Made Easy, agreeing to the shipping charge of $6.95.  I used my check card for the order, and when I checked my balance I was negative because this company mysteriously charged me an additional $40 for these "free" cards.  I called the company immediately to complain, and they did agree to refund my money (almost too readily, because they know they are taking the money dishonestly), but of course they don't take any responsiblity for overdraft fees, and they are benig EXTREMELY pokey about replacing this stolen money.  They also claimed that I chose this option that was going to charge me the $40 which is so not true.  I even checked the checkout page again and there is no $40 fee listed anywhere.  Nor was it listed on the receipt I received by email or on my confirmation page.  This company is very dishonest and I will not deal with them ever again.
