Sales tax

In accordance with applicable state law, we are required to charge sales tax in the state of Colorado (where Speed Stacks has operations) and California. Sales tax is applied to the total amount of the order, including shipping and handling charges and is based on the shipment's destination state and local sales tax rates.

Items on Backorder

From time to time, a Speed Stacks product might sell out of inventory (be "out-of-stock") and be placed on "backorder".

If your order contains only an out-of-stock product, your order will be held and will be shipped when Speed Stacks receives the item in inventory ("stock").

If your order contains both in-stock and out-of-stock items; the in-stock products will ship by the method you selected. The remaining backordered items will ship when they return into inventory.
