I went to buy one of your books using the 1/2 price deal. I was told that I was getting 1/2 off, but the final total on the bottom of the page was the original amount.
I went to the next page to see if I would be told the amount charged to my credit card, but a number wasn't given and I wasn't willing to enter my information unless I was sure I was getting the 1/2 off.
I received an invoice in my mailbox for the correct amount, but the book is gone from my cart. The system needs a little work, I think.
