RE: I did good
A lot of times whether it be a swap meet or a normal sale you just have to be ready for the deal if you want it. I was at a swap meet last Spring and I had set up two tables and I sold almost everything I had, but then I price my stuff to sell. I only brought one box back home with me, except for one purchased item.
To me I sell the same as I would expect to buy and it works for me. Even on normal sales, I price the planes super decent and always tell the purchaser if for any reason that there is disatisfaction I will refund and take the plane back. This has always been my rule and I know I would not make a good businessman because I cannot gouge anyone. My conscience doesn't do well with that practice.
I kept eyeing a Goldwing plane at a swap meet last year that I liked and had been looking at on the web at the plane for some time so I knew I wanted it. A guy had one in the box and had a decent price on it. It had sit all day with many looking but none buying. As we were packing up I made him an offer that I felt like would have basically gotten plane for a good price and he would be satisfied as well.
Sure enough, he agreed and we were both happy. I talked to his wife a bit to make sure it was a reasonable deal for him. I did not try to cut him down to where it would be an insult to him. I put the plane together and she is one of my favorites!
