Not sure if anyone has been following these coolers but they became available around a month ago. Immediately sold out everywhere, went like hot cakes. They've sat around £160 on Amazon since from third parties, but are not available from Amazon directly.
The price has now been lowered to £145.46 while they're out of stock (directly from Amazon). This is the cheapest price on the net, as far as I can see.
