You posted the shipping faq on the forums on here, and I'd just like to add that if you ship through USPS's offices they provide free boxes, envelopes for shipping and even tape if you just stop in the post office. At least they do around here, I ship a lot of stuff through ebay and they just have it all laying in there and you can, if I'm not mistaken, order it from them online for free. The trick is, it's all marked with their 'brand' of postal service and you HAVE to use their courior and not DHL or whichever else.
It's pretty helpful and I didn't see it skimming through your post so I figured I'd let you know so others can too.
