i've just never been able to get coupons to work, but i do the "flybuys" or those cards through the grocery stores where you get the lower prices, which saves a fair bit, and i buy direct from the farms. i honestly do not have the time/mindset to coupon.
also, most of the stuff is crap, imo, and not stuff i use. *if* i find a coupon for something i would use, then. . .i use it. LOL but it's usually just luck.
