Is Airventure 2019 a good place to order materials?

Are there "show specials" on sheet aluminum and steel tube?

I was inclined to skip Airventure 2019 (I've only been once before) so as to save money to begin a project (I have Bearhawk LSA plans).

On the other hand, if discounts are available for show-goers then it might makes sense to make the trip.

Thanks in advance for any experienced advice.
