Not cards, because once I have it I don't need more and stop looking.
However, I was at a model show in Minnesota this past Sunday and bought a kit for $17. At the other end of the show there was another copy for sale for $5. To add to that, the one for $5 was a table run by a friend and I would have liked helping him out by not having to bring the stuff home. (He was more interested in clearing space rather than making a profit)
Smacking myself a bit for that one, but at least he did sell it to somebody. Maybe someday I'll even actually build it.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
