No charge for shipping on this one, and I probably have the lowest Buy It Now presently being offered for this pickup.  Because the price is so reasonable, there are no returns accepted on this item.  It's brand new, and I only got it to admire it (tired of that, obviously), though, so you can be confident it'll work as advertised.  Free shipping is to the lower 48 United States only.  If you live in Alaska or Hawaii, or are using an APO/FPO address, and you intend to bid, please contact me so that I can give you a quote on mailing it to you, and a modified invoice if you purchase this pickup.  Sorry, but no international buyers please.  I also offer local pickup on this item.
