Free shipping applies only to standard ground shipping within the forty-eight (48) contiguous United States, on orders that have items that qualify for free shipping. Only the items that qualify will get free shipping; orders that have both items that qualify and items that do not qualify will see shipping charges for the items that do not qualify.

Items that qualify will have a free shipping indicator on the item page and in the shopping cart.

Free Ground Shipping is automatically applied in the cart and checkout.
