I used them to advertise for me locally. They print and deliver (through USPS) a twice a month paper with nothing but advertising in it. You can specify (to a point) what area you would like to advertise in, and they will make up a page for you. You give them an idea of what you would like, and they come up with an advertisement, (color / black & white), in the size you agree on (full page, half page, quarter, or eighth of a page). I got a half page on the back (prime area) for 300.00 and it went to 10000 homes. As it may work for some, the advertising did nothing for me, and I would never use them again, even if they drastically lowered the price. I don't think it is as effective as a single flyer or postcard from your business.
