Shipping Methods & Transit Times

Free Shipping

We offer Free Shipping on eligible items within the contiguous 48 United States. Outside this region, we'll provide an accurate quote on request. Some oversized or freight items may not qualify unless specifically noted.

Freight & Oversize Shipments

Oversized shipments travel via Freight/LTL, designed for commercially zoned properties — deliveries to non-commercial addresses may carry additional charges. When receiving freight, inspect the package for damage and note exceptions on the delivery receipt before signing. Extra services like a lift gate incur carrier fees payable by the customer.

Canada & International

For Canadian shipments, customs duties, taxes and brokerage fees are the customer's responsibility — please pay promptly to avoid delays. We ship internationally too: if your location isn't supported at checkout, contact us for a custom quote. International customers are responsible for duties, taxes and customs charges.
