Pricey at $28 a pop, but probably the only way at this point to snag the trailers. When they were on Amazon at 50%-75% off MSRP, I bought some for the trailers and sold the flatcars on eBay where they fetched $10-15 a pop. So, if you really want one of the trailers, you can shave at least $10 off by selling the flatcar (which is almost cartoonish in appearance). Low quantities on hand.
