If you sign up for the 'Daily Dose', you will recieve an e-mail that gives some of the upcoming items for the day. Generally, in a clever little blurb. You can add SAC to your personalized Yahoo or Google page. It doesn't update as frequently, but it shows the last four or three, respectively, items. However, if you click on an old item, it will link to the current item. So, you don't know the price of the old item, just what it was.
Another good site is DealSucker.com - deal of the day monitoring tracker aggregator
. It compiles several 'deal of the day' pages, including SAC.
