It takes a lot of time and materials to properly pack and ship a heavy machine. I've only shipped two and it took me at least an hour and probably $25 worth of packing materials for each one. I completely understand why they choose not to do it. The materials may cost more than the profit from selling an item. It's interesting how most GW locations do ship and a few don't..
It's very nice of Rodney to do this and it's great that we have a network of people to help us when needed!
