Slickdeals is perfect if you love to find deals but want a site to sort of round them up for you.  The site features user submitted deals that viewers can rate based on if the deal is actually good or reliable.

1SaleADay is a daily deal site that has 4-5 specific items on sale per day.  The items are changed at 12am EST.  I have seen deals such as a $300 Polaroid camera on sale for $60 and even the occasional free item (free shipping also).

NoMoreRack features 8 deals each day.  At 12pm EST they add new items.  Items range from clothing and accessories to pet and outdoor.

Amazon Mom is great for moms to save money on baby related items.  You can even subscribe and save to save up to 30% on diapers and wipes.  Amazon Mom features free 2-day shipping just like a Prime membership does.

Fat Wallet is much like Slickdeals.  Users can submit deals to forums, however there are featured deals and coupons by well known stores like Amazon or Target.
