All,
Halfords have got back Edge 800's GB Discover packs for £256.99 (281.99 less £25 at checkout)... less more if you use topcashback and the like. These are the ones with the whole of the UK in 1:50k.
I ordered one last week before they ran out of stock & it arrived a few days later. In fact, they're now a couple of quid cheaper still.....
Cheapest from anywhere by a LOOOONG way.
(They also have the road pack with HR and cadence for a few quid more)
