Tollers said:Cheaper at wiggle when you consider P&P (but not in stock).
Should also be able to get 5% cashback via Quidco or topcashback.
Also, if you subscribe to their e-newsletter, they will send a £5 discount code (http://www.wiggle.co.uk/h/option/Vouchers#vouchercodes).
Of course, you'd have to wait for these lights to come back in stock...
