USPS API – Rates

Basically I’m needing help with understanding how to best serve our customers. Right now our USPS integration returns a lot of rates that are difficult for clients to deal with, such as:

USPS Priority Mail Express 2-Day
USPS Priority Mail Express 2-Day Flat Rate Envelope
USPS Priority Mail Express 2-Day Hold For Pickup
USPS Priority Mail Express 2-Day Flat Rate Envelope Hold For Pickup
USPS Priority Mail Express 2-Day Sunday/Holiday Delivery

This is not a great experience for the shoppers. I’m trying to understand how to simply this, so our clients can simply choose “Priority Mail” as a shipping option, for example.

I’ve reached out to USPS, researched other websites, looked at other ecommerce platforms, and honestly I’m at a total loss on how to simplify USPS rates.
