Procedure
A consignor brings their second-hand items in to be reviewed.
After the review, the consignee will return those items deemed unsuitable for resale to the consignor (such as torn or dirty items or items deemed to be fakes, which cannot be sold in some jurisdictions), accept those to be resold, and establish the target resale price, the consignee's share of it, and the length of time the items will be held for sale.
When a consignor's items sell (or in some cases, after the agreed-upon period ends), the consignee takes a share of the profits and pays the consignor the share. Items that are not sold are returned to the consignor (who must retrieve them within a set time or forfeit title to them; in some cases, the consignor may agree ahead of time to allow the consignee to donate them to charity).
