Large flat rate box shipping not available
Why is the Large flat rate box not available for an option to ship? Only the Medium flat rate box is available.

The trick to finding the USPS Flat Rate Boxes and Envelopes is to put a size and weight in, then you can find them.
Enter your package size as 12x12x5 and see if you are now able to select Large Flat Rate Box.
