I have a school order on one of my shows. The school, of course, is tax exempt to get an item for the cafeteria. I put the order in P3 and marked the tax exemption box. No problem with receipt without tax; however, P3 popped up a fax number to send the tax exemption certificate. I've tried repeatedly and the number is constantly busy. I can't submit the order until this goes through. I have 630-261-8587. Anyone have another/correct number? It's not listed in the policies manual with the tax exemption information. I'm ready just to eat the tax money so I can submit.
