I am using USPS as my only shipping providor, however now that I have gotten my account from USPS, and set it in nopCommerce, when the customer purchase a product, the customer is presented with some 12 or so different posibilities of USPS shipping options, ( even media) which it would not be applicable.
How could I set it, so my customer only get, say two options: Priority Mail, and Expess Mail
thank you so much for you assistance
