Where to get aluminum in Triad

[Nissan11]

I'm interested in purchasing a small amount of square aluminum tubing to build a surf cart. None of the places I buy steel from sell aluminum. Does anyone know where I can get about 40' of 1 1/2" aluminum tube in Greensboro or High Point?

Won't have it in stock, but can get anything in about a week.

Dillion supply quoted me $66 for a 21' stick of 1 1/2" diameter 1/8" thick aluminum square tube. Is that a decent price?
