Just thought I'd start this thread where people can pitch in any discount codes seen on the web or in the shops where top dollar can be saved on parts. I will start with OPIE Oils. 20% discount ends. Next time round on such a deal I will be getting the 25L Shell Helix Ultra 5w40 drum (at CJ advice in the oil thread)... PS. voucher code on the opieoils site is 'blowout'
