Try paying for coupons. (Actually, the sellers all specify you are paying for the service of having the coupons clipped rather than for the coupons themselves. Legal issue, I guess.) I'm so pleased with how this has been going for me lately, I figured I'd post about it.
I set up a lot of saved searches on Ebay, and each morning I get an email with links to auctions that match the search. (I also have searches set up for gift cards and other products I'm looking for.)
This morning I saw a lot of (6) $1 coupons for cat food our cat likes. I snapped them up immediately for $1.19. If I'm figuring this right, I'll be saving $4.81 by spending the $1.19, which means I've increased my purchasing power by 404%.
I've learned to be careful about getting more than I can use before the expiration date. I've seen lots of 20 of this same coupon, but passed on them because I'd never use them in time. 6, I will use.
I also use a non-Ebay clipping service, where you can choose individual coupons in the specific quantities you need. I'm using
Since I'm getting so much at Aldi now, there are only a limited number of name brand items I can use coupons for. This targeted approach gives me a quick way to find the specific ones I can use.
