Yes, its true, I'm not crazy, the usps is offering free boxes and other goodies on thier website.  I can't give a direct link, thanks ebay.  But if you go to there site and check out the packaging you will find many items that you can order AND HAVE DELIVERED TO YOU FOR FREE.

Hope you all take advantage of this, its money in your pocket if you do much business on ebay.  Good luck finding service like this at the UPS Store...LOL
