DD 5 recently required attention to some very dry patches of skin. Her pediatrician recommended Aquaphor. Since, I knew I wouldn't have time to wait for a sale, I asked the desk for samples on the way out of the office. They were very generous and gave me samples totaling 2.52 oz. I thanked them profusely for two reasons. One- I didn't need to run right to the store. Two- It saved me at least $5. I often asked for formula checks and samples when my girls were young and I'm not afraid to ask now. A little polite question can save so much money!
