haven't the £1 shops gone down hill?
lots of them near me and they no longer stock these great £1 bargains:
pack of 5 paint brushes (use them once and bin them)
aerosols of primer or matt black
tin of brush-on matt black paint
large and very handy plastic tubs with lids
3 microfibre cloths
2 x double syringe of epoxy
12 pack of superglue
multipack of metric spanners
various car valeting stuff
safety goggles (i'm now relying on the 20 odd pairs lying around the garage)
silicone sealer in white black or brown
prob many more i cant think of and thats just car stuff...
