Ok, so here are some of the links you can use to find your coupon booklets. Or find out that you don't get certain ones in your area!
RED PLUM: If you type in your address, you can find out if you receive the RedPlum coupon booklet. Apparently, a lot of newspapers dropped carrying them about a year ago. However, you can request to have it sent to your address. The website says it takes 5-6 weeks to get your first booklet. I just signed up for mine, since our newspapers don't carry it. :-)
SMARTSOURCE: not sure the link yet, although I can say I know the Cleveland Plain Dealer carries it, since this is the newspaper I subscribe to personally. And if you ever get a newspaper without it, you can contact your newspaper, and they will send you it! (this happened to me this past Sunday)
P&G SAMPLER: Definitely find out which newspaper in your area carries this valuable monthly coupon booklet, which comes out on the first Sunday of every month!
