April1930 is usually asking at least twice what the items sell for on eBay - if marketed correctly (like knowing you have it LOL!) this foot normally sells for $225-$250 on eBay. So not as much as the two spool embroidery or the penguin foot, but still up there.
The interesting thing with this listing, the seller posted a "question" where someone asked them if they would accept $35 on a "buy it now" the seller responding that they would have, but there was already a bid. Bet the seller is really happy they didn't go that route!
