Recently I had the cause to have all of my prescriptions transferred from CVS pharmacy to Rite-Aid on 7th Street. The pharmacists there are most friendly and helpful.
It is very simple to call in your prescription and have it filled. They always take the time to ask if you have any questions and to explain any side effects that a particular medication may have to you.
Since I am a fuddy-dud and it seems as though most credit card machines are different I can never remember how their's works; but they are always patient and help walk me through it.
