Inventory Disclosure [Abstract]
Inventory Disclosure [Text Block]	2 - INVENTORY Inventory, consisting principally of products held for resale, is stated at the lower of cost, using the first-in, first-out method, and net realizable value. The amount presented in the accompanying consolidated balance sheets is net of valuation allowances of $4,759,000 and $5,893,000 at December 31, 2020 and 2019, respectively. Based upon regular evaluations of inventory to identify costs in excess of the lower of cost and net realizable value and slow-moving inventory, we increased our reserves by $0 and $405,000 for the years ended December 31, 2020 and 2019, respectively, while also applying $1,134,000 and $1,701,000 of our existing reserves to the underlying inventory values during the years ended December 31, 2020 and 2019, respectively.
