I've got 3x B and Q,, 2 of each Tool Station and Screwfix, a Whickes, TWO Beesley and Fildes, a Travis Perkins and a local hardware store within 10 minutes of me.
I bought a sheet of 18mm plywood (to make some jigs with) from B AND Q last Saturday because none of the others came even close on price. I bought a bag of 'pick and mix' screws will I was there too...got a couple of hundred screws in a bag for a fiver. Screws sizes I don't use often, so don't need boxes of.
I may not use B and Q again for a while ...but it is useful at times.
I haven't bought any kind of tools from a walk in shop for (possibly) five years or more. It's always cheaper online.
