Where do you buy your coroplast?
 

I looking for some black coroplast.

Wanted to know where everyone buys their coroplast. Locally, I found a sign shop selling 4x8 (black) for $20 which is a bit pricey and does not fit in car, as is.

Online, I found the best prices at

Beacon Graphics 2x3 for $2.30 s/h for 10 - 50 sheets is $12 - $20 (black)
Harbor Sales 2x3 for $1.91 includes s/h (white)
Harbor Sales 20" circle for $2.06 includes s/h(white, I hate cutting circles. 24" cost 50 cents more).

I buy it at the lumberyard where I can carry it home by hand in under 5 min. To carry 4 X 8 finished signs in the back of a metro, I slit the back so that they folded in half, and then bent into an arch to fit through the hatch.

I got three 4'x8'sheets of black 4 mil coroplast at a local sign shop at about $11 a sheet. Had to strap them to the roof, but I brought them home. I need to go get another, since I'm just about out. I want to redesign my wheel skirts, but I don't have enough. The kammback ate most of my remaining material.
