First time posting so apologises if i get something wrong :)
I know there's been a post about this TV involving the Costco website but...
Just price matched this TV with AO.com quoting the Costco website. After 10 mins of being on hold and speaking to a senior sales member, they finally matched the price saving me £230 (£100 of that was knocked off in their sale)
Costco state a 4 working day delivery slot but have rang round my area and been told all their North West branches are now sold out and do not know when the next batch are due for delivery. So for an extra £20, AO will deliver your TV TOMORROW!
