Apparently "there are ways", but honestly I can't think of any. Nintendo's a publicly traded business, the 3DS's original price having to be cut caused Iwata and many other executives to lower their salaries, Kimishima himself has said that price was a major part of the Wii U's failure. Whilst it may not be £150-£200 low it will definitely be nowhere near the Wii U or possibly even the 3DS at launch.
"Can be found for" is not the same as retail price.. You can bet no matter what Switch's retail price is some stores will be selling it cheaper, same thing happened with 3DS (even pre-order you could shop around and get significant money off).
