      • A restocking fee of up to 25% may apply on certain products, depending on the product category.

   4. Manufacturer Part Numbers:

      • Many manufacturers (such as HP, Dell, IBM, and Compaq) assign corresponding Spare Part Numbers (Spare P/N#) or Field Replacement Unit Numbers (FRU#) to their products.

      • The received item may display one of these numbers, which are valid replacements for the ordered part.

      • Additional warranties (manufacturer, service, or extended) may also apply depending on the product.

   6. Product Packaging & Accessories:

      • All items are bulk equipment and typically do not include drivers or CDs. Contact us to confirm availability if you require installation media.

      • Product images are for illustrative purposes only—the actual product may differ slightly.

      • Packaging may vary (e.g., OEM or plain bulk packaging) depending on stock and order quantity.

      • Refurbished printers may not include toners or full ink cartridges.
