Don’t be fooled into thinking that it’s only high-end retailers that stock hugely overpriced gifts. The next three are from Amazon, that most universal of retailers. Whether it’s due to Amazon’s strange auto-pricing system that pushes the price up if stock is low, or whether you could genuinely spend the price of a house on a website best known for books and CDs is unclear but should you want to do the latter, why not start with the Millage Flying Tourbillon watch – currently priced at $99,000. It comes in several colors, has a watch made from alligator leather (what did these alligators do to the makers of luxury goods?) and a 7-year guarantee. The reviews may be somewhat cynical and possibly not entirely true but don’t let that put you off if you’re looking for something very, very expensive to put on your wrist.
