Fortunately Wickes has a ready supply of Spax screws in small boxes as well as packs of 200 which is about 160 more than I'm likely to need for the rest of my life.
Screwdriver bits: I need to wreck all the ones I've got already: Bosch, Stanley, Draper, Black & Decker, someone else and the one I found in Mr Sainsbury’s car park the other week.
