1. It was a bidding war between two bidders.
2. You never know what the seller said privately about the contents. I have had long email conversations about items that never were shown on the listing.
3. If you like that, I know a lady with a living room full of the same stuff and she was having a garage/living room sale last week. Only one bolt looked newish. Piles and piles of earlier fabric.
Once I got a car trunk load of 70s vintage (probably hundreds of yards) for $75. Properly stored and the leftovers from an ebay reseller. Great fabric for our donation quilts if even used for the backs. We used it for a year.
