I usually just buy materials from Screwfix when doing little jobs of my own but I was at the firms wholesalers so paid for an MK 1 gang socket and 25mm back box...£6.40. I then thought I'll just search Screwfix...£2.93! Now I thought Screwfix would be expensive but its the obviously the wholesalers! I just dont understand why a trade place would be more expensive than a big DIY place! I had the same problem the other week when I went into B&Q and got some stuff from tradepoint and one thing was an MK 1 gang switch £1.38. The sales person then told me that some of the other stuff I needed was on the main shop floor and then I saw the MK switches for £1.08! I queried why the trade counter was more expensive and he said that it must have been the wrong make and I said that I'm not stupid and know MK when I see it! His reply was do I really want to walk all the way back to save 30p! They even had them online at £1.08 when I checked! No wonder customers just go to to the big DIY stores!
