Save on Colgate Total Advanced Mouthwash at Rite Aid! This week, the 16-ounce bottles are on sale for $3.49. I found the bonus-sized, one-liter bottles at my store, tagged with the sale price. Purchase one bottle and use a $1.00/1 coupon. At checkout, receive 100 Plenti Points ($1.00), making the final price $1.49!
