You can ask right near the entrance.
Hmmm that's a good question. I don't remember either of the memberships stating that you can. It may be worth your time to ask at the service desk. Its to your right as soon as you enter. I do know with my plus membership several prescriptions are available at No cost to my family
Sam's club help desk should be able to answer that for you
Call and ask
No clue. Check with HR
