Shipping LCA's via USPS

Nope, they won't.

When i sell LCA's i get them in a box 16 X 16 x 6 that i use.
With packing, it weighs in at 27, 28 pounds.

Believe me, they are not Cheap to mail out thru the USPS.
I now send thru the UPS, using the "Pirate Ship" discount shipping firm, that you may have been reading about, here on this site.
