Requirements / Restrictions

  • All returns must be started within 30 days of the order's ship date.
  • All returns must include an authorized RMA number on the outside of the package.
  • Any item listed as discontinued or being phased out is non-returnable.
  • All items marked as "Quoted" or "Special Order item" are non-cancelable and non-returnable.
  • The costs of returning non-defective products to us are the responsibility of the customer.
  • In order to receive a store credit or refund, products must be returned in working order and in their original, undamaged packaging.
  • All orders shipped outside of the USA/Canada are non-returnable.
  • We will not be responsible for covering defective products for orders shipped outside of the USA.
  • We do not offer expressed or implied a warranty on any items. Any issue with a warranty claim must be handled directly with the manufacturer.

Restock Fee

  • If a product is returned and is in full operating order, a restocking fee of 25% will automatically be deducted from any refundable amount.
  • If an order is returned without authorization or an RMA #, a 40% restocking fee will be deducted from any refundable amount.

Why is there a Restock Fee?

  • When we process a return for non-defective product, we have significant labor costs to process the inbound shipment and to test that product is valid for resale. And if/when we return special order products to the manufacturer, we are assessed restock fee ourselves.
  • Our restock fee is standard for the industry and less than what the manufacturers charge us.
