I live in CA, so shipping is expensive. My 1st York I bought a brass engine and carried it in the box with me through the air ports and on the plane. Won't do that again!
Getting good deals on cars or engines is somewhat lost for me if I have to turn around and ship the stuff home. My 2nd York I bought a couple caboose(s) that were hard to find, and carried those on the plane. I bought a ton of detail parts, figures, and other small items that went into my luggage.
For the most part, it has to be a really, really great deal for me to buy at York and ship home. Most of the stuff I can find online once I return home, or I just have to live with out. I do a lot of recon there, like checking out all the stuff at the Scenic Express booth to see what the stuff actually looks like, and make a list. Even that is better for me to come home and buy it, so I don't have to worry about shipping while in York.
Now if I lived within driving distance of York....., my wallet would be in serious trouble. Good thing I don't...kinda.
