Please help me! I will be building a greenhouse and need 14 x 24 in 6mm polycarbonate panels for the roof. I have looked at greenhousemegastore and polycarbonatestore and the shipping is equal to the cost of product. Does anyone know of a local dealer in Eastern Tn or have a lead on another poly online store? Or any other ideas? Thank you!
