Does My Order Qualify for Free Shipping?

Qualified orders over $99 will ship to you without incurring a shipping fee. The following guidelines should be taken into account:

The free shipping option allows TubeDepot to choose the most appropriate carrier and service.

Domestic US shipments under 1 pound usually ship USPS First Class.

Domestic US shipments between 1-7.9 pounds usually ship FedEx Ground or USPS Priority Mail.

Domestic US shipments over 8 pounds will be subject to shipping fees. If you place an order for a heavy or bulky item over 8 pounds, you will see your shipping options at checkout. Since TubeDepot is in Memphis, TN, the home and main hub for FedEx and USPS, we get very good rates, so rest assured your heavy item will be shipped at the most affordable rates.

Free shipping is limited to the contiguous 48 states. Free shipping is not available to Alaska, Hawaii, U.S. Territories and Outlying Areas, APO/FPO/DPOs or International destinations.
