Free USPS Priority Mail Shipping Boxes

I would never of thought to bring this up, until my brother came over to my house the other day and said "Sherry, I am hooked on Ebay"... I said "Why now?" (He knows that my husband and I are sellers on Ebay and have been for a long time!) He replied "It's so easy, and I didn't know you could get free, priority boxes from the post office!" I was like "Hello" we have been doing this for years now, where have you been?" My brother does not listen to anything I tell him, obviously...Is this a "Big Sister" thing? Anyway, if you decide to start selling on Ebay, Simply go to http://www.usps.com/, sign up, place your order, (you will have several "priority" boxes to choose from) and they will deliver them to your door, FREE. That Simple!
