Saw this in an email Base.com sent out last night, part of their "Half Term Games Clearance".
The price for Nier Automata is actually listed at £37.85, but as always with Base.com, make an account and set your postage details and it will remove VAT at checkout for the final price, which is £33.03 delivered (~AU$53.73).
It was listed higher a few days earlier (£40+) so it's a decent pre-order deal, and you probably won't find it cheaper locally.
