The Wal-Mart order is a significant part of the inventory.
From the 10-Q: "Inventories have increased significantly since December 31, 2008, but this increase is planned and normal due to the seasonality of the Company’s business. A more appropriate comparison would be to September 30, 2008 inventory of $5,449,191. A significant portion of the increase in inventory is related to the large Holiday Promotion order from Wal-Mart for the Company’s Deluxe Gun Cleaning kit that shipped in October 2009. The increase in accounts payable is directly related to the increase in inventory."
