InvInventory Disclosure [Abstract]
Inventory Disclosure [Text Block]	3. First-In, First-Out (“FIFO”) based inventory costs exceeded Last-In, First-Out (LIFO) based inventory costs by $138.5 million as of the end of the first quarter of fiscal 2013 as compared to $96.4 million as of the end of the first quarter of fiscal 2012. The LIFO Reserve increased by $1,262,000 in the first three months of fiscal 2013 compared to $6,527,000 in the first three months of fiscal 2012. This reflects the projected impact of decreased inflationary cost increases expected in fiscal 2013 versus fiscal 2012.
