Marine Landscape Sweater

I have seen this Marine Landscape Sweater/jumper for £ 990 on ebay approximately one year ago and it is still there....

Aside from the fact that it is overpriced (probably the lady wants to prove the point that she has designed it and, like all designed items, it comes with a heavy price tag), I am just wondering how much it cost to keep the auction going... Probably she must get some additional work from it, otherwise she would not have the patience to wait for a buyer...
