This error has been received since last Thursday when I try to checkout with my internatinoal shipments on USPS.com:
We are sorry but an unexpected error has occurred during the checkout process. Please try again later.
Of course, nobody at USPS has a brain or can help me fix this. I have over 20 packages that need labels. It would take someone at the post office more than their scheduled shift to create labels for each of my boxes. I simply do not have the time to take them in.
