Do you need to have membership to buy alcohol?

Yes, membership is needed

You need membership to enter the building although I guess you could say you're going in to enroll so you could use the snack bar, but to buy something at the main checkout you must have membership. However I think due to some NJ law, you do not need membership to use the gas station. But they only take Visa - no cash.

Yes

What do you think? Yeah.
