One of my favorite shopping malls is http://www.eoutletcenter.com and http://www.eoutletcenter.net. They offer comparison shopping of over 1.5 million products. And they post coupons and sales. They seem to do well with clothing and apparel. Try a search in the search box and select "PRODUCTS". You'll be able to view a number of products that match your search criteria. Let me know what you think.
A neat trick is to use the word "coupon" or "sale" in the search box, then select a Store Search. You should see most of the coupons and sales that are currently posted by the various merchants.
