For a few years now, there has been a dramatic increase in online “deal” Web sites where subscribers can get bargains on a variety of products and services. These “deal a day” Web sites typically offer (for a fee) localized coupons or gift certificates good for dining, beauty services, auto repair, cosmetics, cosmetic dentistry and a variety of other goods and services. The defacto standard is “half price,” but I have seen discounts offered in excess of 90 percent.
