Are these showing on a special "sale" page? A search for AF returned a total of 39 items on 2 pages (which also showed an HO Bachmann set, a couple of Lionel O scale items, plus a classic Gilbert Defender set). The Milwaukee Northern was shown @ $299, as well AF lettered waffle box cars, and a couple of cylindrical hoppers, along with several Fastrack items at about 20% off list, and although the Northern is a great price (is it Bluetooth capable?), the list didn't indicate there was a special huge sale going on,unless I missed a link somewhere.
