Hello, I've been running this Drupal 7 / Ubercart store for a year... works great. Shipping has been with UPS. We are tying to add USPS and I believe I've done everything right... but it doesn't show up for the customer.
- all ubercart / related modules updated to latest official release
- In store config, turned on: U.S. Postal Service (Parcel)
- Put in user id.
What else do I need to do? Thanks.
