They posted somewhere about it, but one of the services (USPS, UPS, FED-EX) has those "anything you can fit in it for one flat rate" boxes that can exactly fit two bags if I remember right, so they get a great deal on shipping at that level. Was something like a story about someone ordering like 300 bags and it turned out cheaper than shipping a couple pallets truck to ship 150 little UPS/USPS/FED-EX boxes. :smoking:
