Again, it would depend on the actual operating costs associated. Consignment inventory sitting in a distribution center or with a dealer is still inventory, and somebody has to bear the cost of ownership. My business has converted much of our inventory to consignment, but it comes with associated costs such as reduced payment terms to the supplier (net 60 vs. net 90 say), and aging credits - that is to say that we hold that inventory in consignment for 90 days, but at the end of that period we own it outright regardless of usage and must pay for it at that time. The only incentive to us (and by extension our customers), is that it should effectively reduce lead times, because I have the material on hand. It's a gamble I take in my MTO business because I am constantly analyzing my Backlog, Sales and Costs.
Again, if you are talking about mid-fi components in Joey's case, it will still be much easier to cycle or turn that inventory, but if you are talking about botique brands they will either not consider consigned inventory, because they are just as strapped for cash as the store operator would be, or if they are a publicly held company that deals in higher volume, they have a responsibility regarding that cash to their shareholders who are expecting it to yield dividends. Inventory is nothing more than stagnant cash that doesn't earn anyone anything. You have to sell it off at a profit to make money regardless of whether it is at the Maufacturer, Distributor or Seller level.
