I did this with 2 other games that allowed it years ago and loved it. Made some nice hobby money. Didn't last long though. They stopped doing it. Heard you can do the same with this game but I know it usually doesn't last. Only one game comes to mind that has been around that still allows it. Sorry, don't know if rules allow me to mention other games, so that's why I didn't. Anyway, wondering if this is still allowed, thanks.
