You can also sign up (for free) on USPS for their "click and ship" which you pay online with your debit or credit card and print out your label(s) from your home printer. You have the option to arrange a scheduled pick-up of when you want the package(s) to be on their way to their destinations. Also, make sure that when you're on-line to schedule your pickup of the packages to put in the comment section where they'll be located, such as your mailbox or the stoop if it won't fit in your mailbox etc. They'll come pick it up at your door during their deliveries to your neck of the woods. Tracking #'s and all are included as well in the price of the box. Just stop in at the post office when you have a free minute and look for the kiosk that has the flat rate shipping boxes. Stockpile a bunch for yourself so you don't have to make that many trips to pick some up. People stare me down sometimes when I take most of them and then I get the evil eyes and dirty looks from the employees who then have to follow behind me and re-stock haha.
Also, plastic bags from supermarkets or wally world, bubble wrap or newspaper are pretty good to keep the smokes secure during transit. You don't neccesarily need the bubble wrap but I'm sure in time you'll stockpile some of it. Sometimes, (ok that's being way too nice) A LOT of the time, USPS isn't very gentle with the packages they're sending to their desinations. And don't mention anything of tobacco...
