Thank you for the great information.
I am doing a track at Michigan International Speedway in May and this is just what I needed to help make it happen.

Their price is $0.35/foot if you go there and get it direct. It doesn't matter if you get a 100 foot or 250 foot roll, or if you get 1 roll or 20 rolls. Its a straight up $0.35/foot, so its easy to figure out how much it costs.
If you don't want to drive there and live in the midwest, Carter Lumber is one of their distributors.
http://www.carterlumber.com They have stores around the northern midwest. Generally it is marked up 40-50% at hardware stores though, so going direct is your best bet. I was able to fit 9 rolls of 250' tubing in a 16x7 foot trailer and the bed of my truck.
If you don't live around there, ask your hardware store if they can get product from Baughman Tile. Otherwise, it is often marked under the "Poly-Drain" line of products in their catalogs. Its the same stuff from the same place.
