Does anyone there buy golf balls?

Yes yes yes

Check with vendors

Some might buy them. Most vendors start to CLOSE around 3:00pm winter time hours Friday Saturday and Sunday 9:00am to 4:00pm.

Plenty since I known the place.

I know the man who sells golf balls, has a large selection. He is in the last building. Good guy.

I saw some in September

Not sure. I know a few vendors sell used ones so I assume so.

I know they sell them there.

A lot of vendors have already shut down so when I was there Sunday I didn't see any
