Bulk/High Value Order Returns

Due to the labor required to package and ship bulk orders, as well as cost and stock issues involved in replenishing items, bulk orders of 5 pieces or more are not returnable unless the equipment is defective or mis-advertised, or a return period is prenegotiated. For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.
