UPS WorldWide Express Economy is a service that allows you to group multiple shipments going to the same country together. This can save you money if you frequently ship lots of items to the same destination.
Note: This service is only supported when using your own UPS account. It is not available using Veeqo's UPS Discounted Rates. It is also only supported when shipping individual orders and not on the bulk shipping screen.
