So this "Special Offer" was a LivingSocial deal. I would agree with you but I looked over the email many times, and my own account page. There is not only no easily visible option to cancel, there is no email contact. I have to call to complain.

Even more befuddling is that every Amazon purchase I have ever made has resulted in a confirmation email minutes after the purchase. This "Special Offer"'s confirmation came to me at 2AM, well after I went to bed. I'm willing to chalk this up to me mistakenly hitting the buttons and ordering the offer while awake and that there's a delay to process it on the LivingSocial end. Either way, it was not reassuring.
