UPS CMS Processing Fee
None
If you recently have sent any package via the UPS store, look at your receipt carefully. On it you'll see a line item for .20 cent for "CMS Processing Fee."
A quick search around the Internet shows that the fee is for using the iShip product.
The services give corporations, like UPS, Shipping Insight to make the smartest shipping decisions. Employees in any location can price, ship, track and manage important shipments over the Internet through easy-to-access iShip hosted applications. Managers and Administrators also have complete control and visibility into shipping throughout the enterprise and are able to define shipping procedures, approve carriers and rates, and set shipping rules.
Basically the UPS Store is charging you to find the cheapest way to send and track your package. There is a PDF document from flemingareaoffice.com that briefly talks about the fee impact.
