Here's a little antique store in West Columbia that I'm afraid I never got around to visiting. Here's what commenter Larry had to say about it:
Small but missed is the Attic Treasures on Meeting Street (I think). It was a typical antique mall with lots of booths offering things from lots of people. It was in this odd building and a bit smaller than most but still a great place to find neat things like an old manual typewriter for $15.
It sounds like the kind of place I would find interesting. I really don't like high-end shops with a lot of antique furniture, I like places with a lot of "old stuff" -- the warehouse antique mall on State Street being a prime example (as was the lamented Dixie Used Furniture in the Vista.
In fact, I bought the first Closing-Cam at an "antique mall" in Fernandina Beach, making it the first "antique" digital camera I'm aware of..
("Hats Off To Larry")
