This will rush the speed at which your order will printed, and a tracking number emailed to you.
This will not speed up the duplication process.
In a normal scenario it may take 10-12 business days for your label to print. Then an additional 4 business day to duplicate and ship. Adding this would remote *most* of the processing time prior to label shipping.
We will do our best to print all rush processed orders the same day, but in the event of weekends etc it may be another business day.
