Check-In appointments are required for those consignors who anticipate bringing over 100 items for sale. If you have less than 100 items then you may arrive anytime during our drop-off hours. It is still recommended that you choose a drop-off time even if you have less than 100 items, but it is not required. You may sign up for a check-in appointment during the registration process or from your account in MyCM. If you are selling over 200 items you MUST choose a drop-off time that is prior to 6pm on the first day of dropoff.
