The claim of higher "overhead" costs does not seem to explain much. But it does ... it requires server space, server maintenance, extra time to perform backups, and a lot of other things we probably don't think about. More space equals more cost to maintain. >> The solution of "oversaturation" and "competition" has always been the same: Make sure that you offer the best products at the best prices and encourage (not discourage) more commerce through the site. A more likely solution would be to remove a product if it doesn't sell a minimum quantity or dollar amount after a certain period of time. This would solve the storage issue, and also entice brokers to increase quality and marketability.
