All orders require 100% payment at time of order placement. Payments are processed online or via phone. Invoices are provided and copies are sent via email, though they are also accessible when signed in to our website. Sales tax is applied at the time of payment and paid as part of the original order. Shipping costs are charged with each order, unless order pickup has been arranged with the LA Warehouse. Any changes to orders, shipping dates, and/or shipping methods may result in additional costs that will be determined at the time of the change request.
