I have bought many things here, They have children's benadryl which is less drowsy (exclusive) and a very good policy on exchanging if something is not right.
This weekend, I ran out of a drug. I transferred it to CVS, as my usual pharmacy wasn't open. They gave me the dose I needed for Sunday, and I picked up the remainder on Monday.
Thank you CVS.
P.S The manager is always willing to work with you if something is not right.
