I, too found a book on DiscountBookSales DBS). When I entered my billing info, the next page displayed a special through Smart Savings Center (SSC). I exited the page without clicking. Today I got an email saying that my 3 day trial had 1 day to go. I did call to cancel and did receive a cancellation email back from SCC. I also received an email from DBS that my book wouldn't ship untill the 20th and my card wouldn't be charged until then.
I also contacted Discovercard and was informed that my "secure card number" was already authorized for the books (no problem, as I did order the books). However, Discover agreed to immediately cancel that "secure card number" so no further charges could be placed by anyone. They also said that if the card wasn't charged in 10-days, the authorization would drop off and the charge could be cancelled.
Yes, I did email DBS to cancel the order
