So Ive noticed most people have no Ide where to find XPVC to build racks with. I decided to start a list so people have a starting point. If you know of a supplier please P.M. me so I can add it to the list. If theres no one on this list near you, try to contact a local sign and banner company as the will sometimes have it in stock. If they are charging you more then $120 per 4x8 sheet of 1/2' pass and look else were but remember that like all plastics, PVC is based off of oil prices and will vary from week to week.
