Not good at least for mail service..
I just had very bad experience on this service center. I have asked for a usps priority mail service, with certified and return receipt service, whole thing costs me 13.90$. And when i checked the rate in the web, it only costs:
priority flag rate: 4.95
certified mail : 2.80
return receipt: 2.30
whole is 10.05
How could she ask for 13.90? And she even asked me to pay in cash, while her reason is cash only for USPS. I am feeling really bad on it, and call her back to check the details. she replied that the difference is the private service fee, 15cent to 4$. How could that be that much? 3.85$ extra for 2 ounce stuff? I am going to dig into whole thing deeper in this service, and are going to check with USPS and other institute later on.
