The problem with selling that on Ebay is that the cost to post it and make sure it's still in mint condition will still cost a lost. Not to mention Ebay/Paypal taking their cut. If I saw that, AND had the spare money, I'd be happy to pay £100 but at the end of the day, it's a luxury and the people who probably have the money to burn and buy it will have already bought one.
Y'know sellers can charge for shipping, right?
A lot of sellers usually offer cheaper shipping in the auction and do a disclaimer stating damage during postage isn't the fault of the seller. Usually offering that the buyer can pay for better shipping to ensure the item isn't damaged in transit.
Ebays "cut" it pretty minimal as well.
