It is worth it to buy two pairs as you get 15% discount over £50, use code BHOL.
With the effects of the discount i technically got the black authentic (not on sale now) ones the other day for £21.50 and the vans era for £26.50 which is the cheapest around, believe me i have searched around for a while.
Also 10% quidco i think? which can save you another squid or two
