Halfords isn't all bad. I buy my Turtlewax and Autoglym stuff there. Of course I don't ask staff for help, as they'd probably don't know what they're looking at haha.
They have a paint, which they can color-match. Its only semi-decent.
Their Bike Hut is not that great. Rather go buy a quality bicycle and parts from independent shops.
Never tried their We Fit tent and never will. Like, if I bought a radio, I'd be scared they'd pry at the center console and poor soldering.
