Best way to swap formula checks/coupons near Albany?

preggersin2011

I was wondering what's the best way to find someone to swap coupons & checks for formula near albany. Right now LO is on Enfamil and I'm getting Similac and gerber checks all the time in the mail box. I don't like the idea of giving my mailing address to strangers either. A friend of mine said she found someone near her online and they would meet at the Target 2x a month to swap coupons before they shopped. How do I find that person for me??
