Update: I went to my local Kmart (SW Murray/Canyon Rd. in Beaverton) and they are NOT participating in the double coupon event (even though corporate Kmart said all of Oregon is). Not sure what the story is, but you might want to call before you go!
Looks like a fairly slow week at some of the usual hot spots, like Walgreens, but Kmart is having a double coupon event, so that may make up for it! Here are links to some good coupon match-ups:
Kmart: (stated policy for this double coupon event is that they will double any coupon with a value of up to $2.00, limit 10 coupons per transaction)
