Starting July 2026, we are now requiring appointments for dropping off any material being brought in for trade credit or possible cash purchase.
This new system replaces our previous waiting list. We will no longer be scheduling quarterly trade-in hiatuses.

Please call the store for additional information and to schedule a drop-off appointment. Donations without needing credit do not require an appointment.
