Do u have to buy a card being a first time shopper

Yes

You can request a pass at customer service

Go in and look around. See if it's worth getting a card. If so, go ahead and get one. It doesn't take that long, then you font have to worry about it.

You can ask for a guest pass if they're offering them. Always best to call your local club

Not aware of anything like that.

There is a slim chance you can get a day pass.
