But I haven't seen any fire sales here in the UK. The cheapest I've found is for ~£160 on ebay from people who bought the $99 ones in the US.
I think I got one from Comet but it's hard to know even if I paid for it, demand has been huge and sites are being down seconds after they lower the price.
Also, people are buying them at the normal price because they know they can return them if they don't get a refund. And since stores don't want to deal with it, everyone is very confident stores will just refund it.
£89 in Dixons? Haven't been able to confirm myself.
