No restocking fee will be imposed on items authorized for return within 30 days if they are in the original, unopened packaging and not subject to a manufacturer-imposed restocking fee. Certain products are subject to a restocking fee. This fee is determined by the specific rules set by the product's manufacturer.
Items opened and returned prior to 90 days after the date of invoice are subject to an additional 20% re-stock fee as long as they are in unaltered, saleable condition. Previously used/installed items cannot be returned unless covered by warranty.
Returns for special order items or items that have been modified (such as an impeller trim) are assessed on a case-by-case basis. If a return is allowed, special order items will incur a variable re-stock fee of up to 50%.
Customers can either ship authorized return items back to Liberty Supply or request a pick-up arranged by us. If Liberty Supply does not receive the items for which a return is requested, the return will be denied. Additionally, if Liberty Supply is not at fault, return shipping costs and any freight charges for replacement or original orders will be deducted from the credited amount.
All product warranties implied are the manufacturer's liability.
