UPDATE: USPS has finally fixed their issues in the last hour or so. 1:15pm(MST)
Due to a problem with USPS right now, Veracart is unable to get Real-Time quotes from USPS. This affects all Veracart customers that currently use USPS shipping.
We don't have an ETA at this time of when it will be fixed...because it's not a Veracart problem. USPS is working on this and we expect they'll have it back up and running soon.
