Which site do I mail grocery coupons (include SASE)go 2 their site & pick coupons I want, they mail them 2 me?

didn't really have time to check out the site, and I thought @ the time about saving it to FAVORITES to check it out later, but I didn't. Wish I had.

How it works: I would send as many grocery coupons to them, as many as would fit in a large envelope with a 44cent stamp. I would also include a SASE. They count how many coupons (or maybe it was the total cost of the coupons I mailed them).

They then post the amount on their website. I go to my account & pick the coupons I want, how many of each, and they mail those coupons to me in the SASE. It didn't cost anything for me. I don't know how they made money on this, because I'm sure they were or wouldn't be doing it. Or maybe they simply used the coupons?

Anyway, I can't find the site now. Thanks for any help!
