As an avowed never-use-Amazon-er, I've always found SpeedyHen to be super-reliable, and almost as cheap. Looks as if they pay their tax bill too! They have the set available for pre-order at under £85 right now, with free UK shipping. Though I'm making no promises.
SpeedyHen it is. Never even heard of them before....and still ordered from them! Pure desperation.
Thanks for all the replies concerning the problems with UK orders.
Here’s hoping availability isn’t an issue once released.
