National Train Show Shopping?

I can’t wait for the national train show, and I’m just wondering what the shopping is like there? Should I continue to buy from discount online retailers, or save up until next month and take advantage of the special show pricing, if such a thing exists.

I have gotten some good deals at the NTS, but ‘cruising the web’ usually finds the best deals. One of the problems with something as large as the NTS is that there is so much stuff there and ‘impulse’ buying takes over(been there, done that…)!
