Why is it so hard to buy parts from people

I would never buy or sell anything where shipping had to be involved from strangers.

I restored my 69 B body and anything used I bought was from guys I knew who were long standing reputable members of the FBBO forum
I bought a pair of rear convertible panels from a member I knew, he drove up from North Carolina to Richmond and I drove down to Richmond, bought him lunch and we did the deal
As it turns out I never used them and now they are safely stored away
Sadly, id like to help out anyone looking for a pair on the FBBO as they are very hard to find in good condition, if you can find them at all but I cant do that
So maybe this summer I will give Tony D a call and see what he's willing to give me for them and a AM 8 track radio I have for a 69 that was redone by Jules
All my other parts odds and ends I will give him for nothing
Im now facing the same dilemma. Im retiring and looking to sell some welding equipment and one machine. I know someone could use it and id sell it cheap. The money isn't the thing, I need to scale down and get rid of this stuff
Im hesitant to get involved in this marketplace or Craigs list BS and im not shipping
I don't know what im going to do
