Questions from gtx333.

I am a older member. In the past I sold parts on this site (B-body). Now I am back and things have changed.
I have a bunch of odd car stuff - A body and B body I wish to move to good owners.
Right now I want to sell 2 GTX Revell models. One is in plastic and never opened and the other
is never been assemble, but not in plastic. Will sell, reasonable price.
How do I sell these items and how do we send money in todays world?
Before it was money orders, I don't think anybody does it that way.
any help would be appreciated.
