Thanks so much Deal Detector!
A reader (Mary) found the Crest Whitestrips Premium Enamel Safe Formula (42 total strips) were on on clearance for $11.48 at her Target. She used the $7/1 Crest Whitestrips Coupon (2/7 PG), so she ended up paying just $4.48!! She said many of the packs still had an OLD clearance sticker on them that said $22, so be sure to scan them!!
