Not a specific bargain, but I was in my local
Halfords yesterday and the bargain bin / reduced to clear section was full of cycling stuff.
A lot of it a bit random and not all of it at massive savings, but amongst the goodies there were loads of
Altura Coolmax socks at £2.99 (I got some of these), loads of arm / leg warmers, MTB gloves at £3, knee pads at £5 and I also picked up a couple of books - "One man and his bike" by Mike Carter (RRP £8.99, reduced to £1) and "Two Wheels, thoughts from the bike lane" by Matt Seaton (RRP £7.99, reduced to £2). One Man and His Bike is proving to be a cracking read too.
Not at all bike related, but I also got an Energizer 12V Triple Socket & Twin USB Adapter for the car - reduced to a fiver! The same thing on the Argos website is a penny off £20.
Got 10% BC discount on everything as well!
