My wife dropped off a package to be shipped via UPS Ground at the PostNet at 1801 Red Bud Ln in Round Rock and was charged $49. When I checked the UPS and FEDEX rates, the actual shipping costs are about $24. There is no disclosure that there is a surcharge - the only charge on the receipt is the line item stating the package is being sent UPS-GND. I can understand a small surcharge or convenience fee, but $25? This doubled the cost of the shipment without providing any benefit. It is not surprising that PostNet does not disclose the fees when they are that excessive. Do not use unless you have $$$ to burn - I know I will not be going back.
