Amazon and John Lewis both had it for £349 if you pre-ordered. The difference is that John Lewis actually had stock, whereas Amazon doesn't get theirs for another two weeks.

You also get the warp charger 30, case and screen protector with oneplus
Looking into the latest rom and launcher, I think oneplus have finally gotten the edge over the pixel software this year. The nord also gets the google dialer, contacts and messaging apps which is the icing on the cake.
