Marketing at gas stations, pawnshops, laundry mats, etc

[Chris Elliott]

Has anyone had any luck, or deals come from, marketing at gas stations, pawn shops, laundry mats, and other local businesses?

I know some of these places have cork boards, but I want to give these business owners some financial incentive to allow me to market in their establishments.

My stumbling block is how would I track the marketing back to that particular business? Only thing I can think of is ask the prospective seller (may or may not be accurate), or get virtual phone numbers for each business I am marketing at (kind of expensive).

Any and all thoughts or suggestions are appreciated.
