I tend not to buy branded goods anyway, and haven't found Asda to be signif icantly cheaper on own-brand than Tesco.
Asda is full of ugly people buying trolley-loads of multipack sweets and cr isps.
The only good things about Asda are £2 whenever they misprice somethin g, and Dulux emulsion when they have it in stock for a tenner.
