Rush orders can be used for all situations where a delivery has to be created on short notice. For example replenishment orders during the season or web orders that require a fast delivery.
Rush orders are typically used during the delivery season to sell free available stock.
Wholesale customers use this order type to quickly replenish stock.
Typical service level offerings could be "order before 3 pm and receive the delivery the next day". Special surcharges may apply.
