Do they sell used magazines?

Call them, they do answer the phone and have two locations in Jax area, although one may just be a warehouse not open to the public.

I've seen some

Actually, we do sell certain magazines .. .of certain decades. We try to buy most magazines from the fifties and older. We have Life mags back to the origin in 1936. We have old Time etc. We have some as old as the teens etc. We have few titles in the 70's and newer, as the low sales does not support the space taken up.

I would believe so place is huge and very interesting 2 walkthrough but I cannot recall if they have used magazines or not but if I had to make an educated guess I would say without a doubt
