For orders that contain multiple cards, choose the Ground Advantage option in checkout. This option comes with a tracking number.

For single card purchases, desktop users know the routine to ask for an invoice and choose shipping options cause its in a window on the right side of the screen. For phone users, it's a different method. For phone users, please click on the shipping tab when scanning your invoice and it will bring up a menu in which you can choose the First-Class option. Its significantly cheaper but this postage does not come with tracking information. I input the date of the shipment as the tracking info to clear the sale from my shipping schedule tracker.
