E - we order our goods based on a maxxed out work week. So if we are slow a week then we have less to order.. Unlike most around here we work on 3 days out meaning when the builder calls we can schedule them upto three days later.. of course as well all know.. the builder HAS to have it done the next day so there is no way of ordering for the following day or what the schedule looks like.. Just order a shitload and call it a day.. Of course on the good stuff it is JIT or sometimes TFL (too fncking late)
