There is something fishy about it.
If you click on "*See all buying options" it comes out that the product is being sold by something called "Infinity flicks". If you follow to see the seller information and then fill in "Adele" in "Serach for other products from this seller" you get a list of products, some of the with more normal pricing, some of them with the same 2000 price - not all of them by Adele. "19" has two prices, £17.92 and £88.34. Very strange.
I wanted to paste the url here, but when trying to click on it I get the message "The Storefront you tried to access is not available using the URL address you typed or does not exist."
So I dunno what it is, but it's not normal sales. Either a mistake, or some collector items (but then they should be an information about it in the product description?), or something else strange.
