Would anyone be interested in a Consignment area of the store?

The advantage to the seller, I handle inquiries and am able to offer more ways for the customer to pay. Also the pipes are advertised, with pictures on a known vendor's website.

The advantage to the buyer, more ways to pay, or if the pipes don't have the reeds / bag you wish, they can be included in one sale.  Plus.. you have a known dealer backing up the claims made about the pipes, at least inasmuch as can be determined from physical inspection.
