Halfords have got many bikes on offer at the moment some half price! The deal get better use your Kellogs voucher and get 10% of the bikes. Plus any accesories (this can be any amount of them on anything for the bike) are half pricem even if they have already been discounted or on offer.
I bought 3 bikes plus mudguards for 4 bikes (got some for my own bike while I was there) a helmet ( £40 ) and gloves. This would normally have cost £593 with all the above discounts came to £295!
