I have stopped there twice in the past two years. I was driving north and diverted about 30 minutes out of the way to stop at the shop. They had a lot more inventory than I expected for convenience/train store. They also had a few items that I've never seen at other stores or shows. The problem is everything was listed at MSRP or above. There were 4 or 5 items I would have purchased if they were listed at market value. I didn't have success getting them to lower the price as the "train guy" was not in the store either time. The lady at the counter told me I had to talk with the owner in regard to price.
This store really was out in the middle of nowhere. I was trying to Google the market value for some items but I couldn't get cell reception.
