I cant really knock Halfords either.
Yeah,some stuff is on the pricey side,like the car radio kits,(as Col found out)and if you want a number plate making.
But I can toddle down there on sunday morning and buy most of the tools,oils and filters I need.
Saying that,we have recently had a Wilco motor factors open not far from me,.......and I think they are open on a sunday.
