I get them from the paper or online. So far I've not had any problems using online coupons and, really, I think grocery stores should get over it! If the manufacturer doesn't like it, they can just pull the coupon. Anyways... if I know something good is coming out and the coupons can save me at least $5 I will buy a second newspaper. $5 is twice the cost + some extra for gas cost to get the paper in the first place. If there's only one or two coupons that I'll use, I just get one paper and call it a day. I haven't tried buying coupons yet, but I've been considering it. DH is adamantly opposed to it, but he's skeptical about anything for the first 5-10 years it comes out.
Okay, yes, that was some sarcasm, but he really is very skeptical! LOL
