i am having a problem finding a coroplast supplier in my area i suggestions from others as to companies to purchase two and three sheets of 4' X 8' at a time i am selling from my car and my sister has the cutter set up in her dining room in a small apartment. we have no where to store extra sheets so i want to just buy as i go but the only company i found that will sell by the sheet has a link that you need to call them to get shipping prices and there was no answer all day Friday at the only number posted on their site. i will try more today.
