I agree. Open longer & at weekends. Stock some stuff that wholesalers don't - but don't stock other stuff that wholesalers do. Order online to reserve stock for pickup.Stop knocking toolstation and screwfix. They are really handy for most small bits and pieces.
Don't get me wrong, I use wholesalers for most stuff, but SF & TS are useful to have around.
Earlier in the year I needed some specialist screws - self drilling and galved for decking. By far the easiest and cheapest place to get them was TS. I also didn't need to over-buy as I knew that worst case would mean day or two for local (to job) TS to get them in (actually had them in stock). That was also long way from home so didn't know who the local wholesalers were.
