We ship with FedEx, UPS, and USPS. Carrier preference is not guaranteed unless explicitly communicated to us.
Orders shipped to PO Boxes often require additional costs and are not eligible for free shipping. Use a physical address to avoid delays and fees.
We ship to Alaska, Hawaii, Puerto Rico, Guam, Northern Mariana Islands and the U.S. Virgin Islands. Free shipping generally does not apply to large or bulky items shipped to these locations. Hawaii and Alaska do have more flexibility with this due to carrier policies. Quotes will be calculated at checkout or by request.
We do ship to Canada for select items. Canadian customers must choose “UPS Standard® Shipping to Canada with no Surprises!” at checkout to ensure proper customs clearance and avoid unexpected brokerage fees or delays. Orders using other methods may be subject to delays or rejection at customs.
Some products are fulfilled by vendor partners and display estimated ship dates on their product pages. Questions about these items should be sent to support@buildasoil.com.
Freight deliveries involve pallets via box trucks or semis. Liftgate service is assumed unless specified otherwise.
Important: Inspect all freight shipments before signing. Count and examine all packages. Signing the delivery receipt confirms that the order arrived in full and undamaged.
