Works well, but has a steep learning curve.
USPS will give you a spreadsheet showing transit times by zipcode given the origination zip code. If this could be imported vs having to enter manually, that would make USPS shipping time calculations even better.

Thank you for your feedback! We’re glad the app is working well for you. For USPS shipping times, you may want to use our USPS via Stamps.com integration, which provides real-time rates along with live transit times — no manual entry required. We truly appreciate your suggestion!
