Some of my fave sites are already listed but others I find really helpful
are
www.southernsavers.com
www.couponing101.com
www.TotallyTarget.com
www.KingdomFirstMom.com (she does the $scenarios for the drugstores but you already know that gig and how to roll ur bucks from there it seems)
I also order coupons when I don't get many in my area since coupons vary region to region~I prefer to order the whole inserts from
www.wholecouponinserts.com
