Shipping is free across the Lower 48. No fuel surcharges, no residential fees, and no liftgate charge on freight orders. The price you see is the price you pay. Read our full Shipping Policy here.

Most orders leave the warehouse in 1 to 2 business days and arrive within 3 to 10 business days. We send tracking the moment it ships.

Anything that ships on a pallet goes freight with liftgate and pallet jack included, so the driver gets it off the truck and onto the ground at your address. The carrier will call you directly to schedule a delivery window.

Returns are 30 days from delivery. For freight deliveries, inspect the shipment before you sign for it. If something is damaged in transit, note it on the delivery receipt and we handle the freight claim, not you. Read more about our Returns Policy here.
