Went to Asda in store and they have this set on a super discount.
Bagged two. At checkout it scanned at 40GBP each, screamed, yelled and barked and got my 40GBP refund (2 * 20GBP). Complained how come there is no "Double the Difference" policy like Tesco (trying to get the sets free), told no, then got offered a 2GBP voucher, well, better han nothing.
RRP 80GBP on lego.com, essentially 75% off
Building starts right after this post.....
To infinity and BEYOOOOOOOOOOOOOOND!!!!!!!!!!!!
Special Note: Allow me to apologise for the first two posters below, who seem to be either unable to read or do simple maths, or both. (Personally really wonder how did they arrive at the "40GBP per set" conclusion").
