I'd suggest pawn shops, thrift stores, or second hand stores.
The tricky thing is that some stores don't have the words "thrift",
"second hand", or "pawn" in their names. Value Village, Salvation
Army, Bishop's Attic, and Good Will are possible sources. They're
thrift stores. Of course, there's also eBay, Amazon Marketplace,
and garage sales.
In my area, pawn shops are going away, and being replaced
with second hand stores. Look in the yellow pages under
"second hand", "thrift stores", and possibly "pawn".
With the third one, it may be by itself, or it may be
"pawn shops". I think that they're going away because
thrift stores are becoming more numerous, and are
more people friendly. Well, at least I think that they're
more people friendly than pawn shops. I guess that it depends
on where they are.
