i have to to use Halfords, much as i hate to, really want a Machine Mart closer 
Do Machine Mart sell auto bulbs 
Who needs bulbs? In 5 years old had 1 bulb go.... but they sell man tools, as you often point out my garage is lacking in them 
Decent screwdrivers - Draper Expert are the ones I like. Tesco sell a similar-ish looking set for around a fiver, thought Draper made most of their tools. Suspect not the same quality as Draper Expert though. Halfords screwdrivers are utter shite.
Decent pliers/grips/wrenches. Halfords ones aren't always ideal, as you discovered. Plenty of other places sell such things. I'd got for the 'quality' versions from each brand (most brands come in cheapie and quality versions - eg Draper/Draper Expert, Clarke/Clarke Pro, Stanley/Stanley Professional).
Generally, the cheapie versions from each brand are pretty crap to be honest, including Machine Mart's standard Clarke range.
Not sure what Shitefix sell. Toolstation (there's one near the Mini plant in Oxford, so only a slight detour) may be a better bet? Or Toolmaster, also in Cowley - an old fashioned place. Much like our own Brackley DIY, which is also worth a look.
