Grab one (or two) big bottles of mouthwash at CVS! This week, the 32-ounce Colgate Optic White Rinse and one-liter Colgate Total Rinse are on sale for $5.99. Purchase one bottle and receive $3.00 ExtraBucks. Throw in a manufacturer coupon to grab one bottle for only $1.99. This may seem like a lot to pay for mouthwash, but these are double the size of the bottles of mouthwash we normally see on sale–and a 72% savings on the regular price!
