My sister and I are often mystified by what combination drives up prices on ShopGoodwill. Being in Texas seems to make bidding twice as high. Central Midwest (like Illinois or Indiana) sees higher prices. I noticed an average FW with accessories go for 1300 a month or 2 ago, but could just make out a penguin walking foot with box and instructions that must have driven the price up. Several of the items in the lot being discussed are listed on the Singer Featherweight Shop as scarce or collectible and currently out of stock:
