Get free Pink Water personal lubricant this week at Walgreens! The 3.3-ounce bottles of lubricant are on sale for $9.00. Buy one and receive a $9.00 Register Reward at checkout! A Register Reward, like a Catalina, is a piece of paper that prints at checkout. Use it on a future Walgreens shopping trip as store credit on almost anything in the store! In my store, I found these on the feminine hygiene and baby care aisle with the other lubricants.
