The standard pack includes Wii Sports anyway, plus one Wii Remote & one Nunchuk, for £179.99.
GAME & Gamestation tend to do bundle deals on their websites, so I'd assume you'd be able to get similar in-store.
These two sites are very handy for stock checking & prices:

Tailored for online stores, but they do tend to mention actual high street deals too.
What other games are you thinking of?
Need extra controllers & other accessories too?
