[Closed] Where to buy a road bike on the bike to work scheme?

Looks like my employer may agree to sign up to the scheme which makes way for me to buy a road bike. I should have about £800 of 'vouchers' to use and can get these direct from the supplier rather than having to pay the 10% which some of the organisations take. Any recommendations on where to go for the best online deals and what could I expect off of a Planet X bike or a Ribble bike for example? The whole thing looks a bit unclear as to what discount I can get. Any advice would be appreciated...
