The link you posted is the original sale. My guess is the buyer found out it wasn't authentic or the seller saw another authentic one sell for higher and wanted more money. The link I posted was the re-list. After my comment she removed the listing and relisted again. Lot of people commented that the bag wasn't authentic so she removed that eventually as well.When I click your link, it appears to have been either ended or removed.
But mickey3509 may have relisted:
