The best current price seems to be £219.95 delivered for just the OneS + Forza.

There have been a few eBay 10, 15 and 20% off codes recently applicable to games and consoles - they seem to come round really frequently at the moment. I wouldn’t imagine Microsoft will reduce the base package price now, but some retailers may do bundles with additional games / controllers for not much more. For example, Curry’s have the One S, Forza, Tekken 7 and Project Cars 2 for £249.95
