We have some businesses in our local area (Tri-Cities, WA) that you can purchase gift certificates at 1/2 price. I purchase these all the time and keep them for gifts or when we are low on money and we want to go out. Here are the sites I follow:
Two for Tuesdays (KNDU station)
1/2 Price Fridays (94.9 the Wolf)
Dollar Deals on Tuesdays (Fox 11) Currently there is a $50 for $25 at Red Apple Market. This isn't the nicest store but you save half price. Here's the current flier.
If you do not live in my area search the net under IncentRev. This is the company that promotes this marketing strategy. This is how I found out about additional sites in my area. We save hundreds of dollars a year.
