Thursday Tip: Why is Square More?
Why does it cost more to mail something square?
Its considered oversized, cannot be machine canceled, and must be handled by hand.
The official statement from the United States Postal Service reads:
Nonmachinable letters such as square envelopes, envelopes with the address parallel to the shorter dimension, and envelopes containing odd-shaped items cannot be processed on today’s high-speed mail sorters and a 20-cent nonmachinable surcharge is applied for the additional handling costs.
