I use www.stretchingabuck.com for matching coupons, etc. I think they are specific for my area, though. But I've found that sometimes the coupons they say don''t exist!!! They will say to look in a certain circular, I pull out that one, and it isn't there. And I've found that, when I get my circular, sometimes they're the same as my mil, and sometimes they're not. (And we live about two miles away, so it's not as if she's in a different area!) And I sometimes have difficulty finding on-line coupons, even those that are suppose to be there.
