Hello,
I am trying to locate First Class shipping packages but it does not appear as a drop down selection when I select USPS as my shipping partner of choice. I just started creating labels through the site and the closest selection is the flate rate padded envelope (12.5 x 9.5 x 1 in) which has a flat rate shipping rate of $7.75. When I was going to the post office to ship the same items they where using first class and it was about $4.60 per package. Any help would be greatly appreciated.
