Our FREE Standard Shipping option to get Horsepower Direct To Your Door® is either shipped UPS or USPS, depending on the weight and size of the item. Because UPS does not deliver to P.O. Boxes, we strongly recommend that you provide a physical delivery address to avoid delaying shipment. If USPS does not deliver to your physical address then we recommend that you provide your P.O. Box on the Address Line 2 underneath your physical address.
All Standard Shipping orders will ship via USPS or UPS, whichever is the most cost-effective. In general, orders weighing less than 1 lb. will ship Priority Mail and heavier boxes will ship UPS Ground. Orders placed M-F before 4:00 PM Central Time will ship out the same day except in cases where an item is out of stock, back ordered, or the order is pending address, phone, or payment verification.
