On Thursday I found all the items on my acquisition list, plus more items that I had to pass up. And this was on the first day.
On Friday, being more cautious, I found two K-Line Heinz Box Cars in the 1920's era for my MTH 4-Truck Shay engine. Now, when the Long Island MTH Passenger cars show up, I can finally put together my consist.
As an old timer told me a long time ago, do you homework, make up your list and try to stick to it, if possible, and be reasonable to the dealer(s) in trying to make a cash deal, always be polite because the next day the dealer(s) may be willing to negotiate a better deal.
Also, help the newbees as they can spend all there money without a second thought.
Lastly, be polite. It always helps.
