Identity theft scam. What do you think?

I found someone online at ioffer.com who was selling gift cards for 50% of face value. This was not a one time deal either. He had tens of "cards" to sell, since they were actually e-cards, redeemable online as a discount code. The catch was that the code would only work with a specific email address that the buyer had to register with. I followed the directions and placed my order. I did not need to enter a payment method because the gift card covered the total cost. However, my order unexpectedly was canceled and I am guessing that the seller accessed my account and canceled my order because I did not enter my credit card information into the account tied to the provided email address. My guess is that he enticed people to buy these cards, knowing that he was losing money, but also knowing that he could steal money from their credit cards. What do you think?
