I have a Kellogs fpc, no max value, no size restrictions, and it states no expiry. Also the $3 Nexxus and an FPC for a Glade Scented Oil Warmer.
My two most wanted coupons are FPC John Fredia Foam Hair Dye, bogo steamers and FPC Oasis.
Would also consider trading for a large amount of 1.25 Oasis coupons from the Allens cans.
