I doubt anyone on here bothered because no one with disposable income cared about the closure...
In terms of people selling park merch online, it never tends to get too over the actual price at retail (apart from maps, I've seen people pay £10 for a Thorpe map!), and Merlin have a history of taking down a few sales on eBay (though granted that is stuff not available to the public, like the Nemesis audio that was sold off and then had to be returned)...
It's an interesting conundrum really, profiteering off a 'charity' auction...
