A reader recently passed along this link to me http://www.shoplocalsandsave.com/. It's a website that offers a discount card for $25. Restaurants and stores that take part in this program have different discounts available, and they are easily searchable on this website.
It appears that only locally owned businesses take part in this program and for every card purchased, $10 is given to a local charity.
I haven't actually bought a card, so I can't vouch for their product. But it's definitely something worth looking at.
