Restaurant.com does specials of
up to 80% off, and the vendors vary over the course of the month. A lot of the restaurants mentioned in these forums participate. Some certificates have restrictions, but they're still VERY reasonable. I also found a way to get points and commissions every time I get these certificates, which is something I do ANYWAY! (PM me if you want to learn how!) Other restaurants participating include Abondante, Mise En Place, Lyons Den, Walter's Basin and more!
Another great local resource is the
Dollar Saver, which I've mentioned before. It has more than just restaurants, though. Water parks, golf passes, salons, landscaping, and lot sof OTHER stuff (besides restaurants).
It really is possible to shop online AND support local business.
