Guy Kawasaki's Alltop.com has several categories of web sites "like a magazine rack". SInce I did not see a "deals" category , here is my suggestion for a deals.alltop.com category.

I am sure there are 100's of other coupon sites if you know of any please let me know through the comments and I will add theem to this list and acknowledge you in thus post.Even if Guy does not accept this category it will still be a good resource to share. I love slickdeals.net but in fair warning be careful as you may end up getting addicted to deals and buying things you don't need. LOL
