Freight Shipping Information (LTL)

Some items are too large to be shipped with a regional carrier, FedEx, or USPS, and we ship these items with our freight carriers.

Please read the information below so you fully understand the delivery process and requirements.

Required Actions

We will need your phone number for the delivery. The carrier will need to call you in order to set up a delivery time. Please make sure the number you provide during checkout is the best one to reach you. If paying with PayPal, please make sure the number on your account is accurate.

You'll need to inspect your package upon arrival before you sign. If your order arrives damaged, you should sign "DAMAGED" on the delivery receipt. If the item is damaged to the point that it is not usable, you can refuse the item.

Please notify and, if possible, send photos of any damage to vminnovations_help@email.spreetail.com, along with your order number. A member of our Customer Experience team will reach out to you with further instructions.
