Fix Addressing to match USPS rules
The USPS Addressing protocol looks for a two-character state abbreviation, so its optical systems can read city, state, and zip+4 all on one line. It would be nice for 1shoppingcart to translate customers' states into the standard 2-character format for printing shipping labels. By adhering to USPS rules the mail might get processed faster than if it's in an exception queue.
Also, why do you stick "United States" between the State and Zip Code fields on packing slips? That's not USPS standard addressing at all! The standard format is something like:
First Name Last Name
Address Line 1
Address Line 2
City ST Zip
Please use the standard USPS format; it makes it much easier on us who copy/paste addresses into shipping software. Thanks!

for some reason, I can't vote but your comment is completely spot-on. There should be a US standard as well as Canadian or Australian or other countries. Also the font size is microscopic!
I will check out MyShippingPartner.com but maybe 1 shop should be their affiliate.

Check out MyShippingPartner.com - it handles this for you and prints Postage Paid Labels to boot.
