2. Receive an assessment and discuss outright purchase or consignment, with eligibility and terms confirmed individually.
3. Confirm documentation, condition, payment and shipping terms before the deal.

For component sourcing: send the complete manufacturer part number, quantity and delivery destination for a quotation.

### Buyback scope
