We use United Parcel Service of America (UPS©) as our primary means of shipping within the continental United States. Orders will be shipped out using UPS© Ground Service after they have been fully built and past testing. Building and testing period can be from 1 to 4 weeks or longer (see: Terms and Conditions of Sale). You will be notified via e-mail as soon as your system ships. You will be given information on how to check UPS© online tracking systems for you to monitor your shipment.
