"When we are selling DEMOS on products that retail at $60,000.00 USD for $16,995.00 then we have to charge a fee."
I am not in retail business, but I thought that when a a store is selling DEMOS, it is selling used items that rarely cost as much as the original retail. If $16 995 is really such a great deal, essentially loss for the seller, increasing a price to $40 000 and waiving auditioning fee may be the way to go. Even now, the line of tire kickers seems to be long. At least if we go by Audiogon clicks.
OP did a good job in advertising these amplifiers. Someone may get them. The question remains, though. How much will be OP’s fee for finally bringing the sale to an item not many were willing to buy?
