Not a single musical instrument company will put demo units in stores free o charge. It is something that has always bugged me because most customers do not want to buy floor samples unless they are going to be sold at greatly reduced prices and we have to pay the same price for our on the floor demo models as the brand new ones sold in the box. Knowing this, I would doubt if any large or small company would ever place their expensive gear in a retail store and not get paid for it. Although the benefits could mean more sales, often time the store that has no investment in their gear might not try to sell this "free" stuff at all because they would have to sell what they've already paid or been billed for.
