Only rates that are visible at checkout are Priority and Priority Express
Before the USPS changed rates and renamed some of their services, all the services I checked were visible at checkout. Now the only rates that are visible at checkout are USPS Priority and USPS Priority Express.
Once you are done, if you have any problem with the shipping services or rates, kindly do the following:
1. Enable the debug option from the settings tab and try debugging the transaction by analyzing the request and response. For more information on debugging, kindly go through our Troubleshooting Multi-Carrier Shipping plugin for WooCommerce.
2. To compare the rates with the rates returned from USPS, kindly go to USPS calculator and calculate the rate.
On performing these things, if the problem persists, kindly provide us with the following information.
