As per the deal posted by mikeymopp you can currently get four pairs of New Yorker/London running socks for £10 (these are normally £3.99 each).
However if you use the code: LJDNI141711 you will get a further 10% off bringing the price down to £9 (plus £2 delivery).
I have loads of these and they are absolutely great and saved me no end of blisters!
Hope this helps some one.
p.s. code will give 10% off anything on the startfitness site!
