This discussion seems pointless. Sure it may be nice if one can be compensated for their services all the time including carrying inventory to display products, but this ignores the fact that people are also driven to reduce costs to stretch their purchasing power. This is true even back to the days of bartering. Asking for fees to inspect inventory generally only works for exclusive high demand low supply products, otherwise the fees would drive customers away and limit exposure to new perspective customers which in our limited niche high-end audio can not afford to do. Sales is like fishing- nothing is guaranteed.
I don’t have much sympathy for retailers. After all, your equipment depreciates 50% as soon as you leave the store.Retailers do not control product depreciation which is caused market supply and demand.
