I have been following another neat coupon deal site lately called We Use Coupons. This site has a searchable coupon database to tell you where you can find coupons for the items you need. There is also a forum where you can interact with other couponers and learn new things, get previews of store sales or get help with making your scenarios.
There are currently some discussions about a Kraft Dressing Money Maker, the 5/23 Target deals, and of course coupon previews of inserts to come. Check them out!
