I always buy Colgate Sensitive toothpaste, Imperial Leather soap and Lurpack spreadable butter, Stork margarine for baking and Clipper tea. Otherwise I buy mostly supermarkets own brands and the saver items too. I buy meat at the butchers if I can get there.
I boycott all things Nestle after the formula powdered milk scandal and Tesco since the tv programme years ago about their policy in Africa and more recently their buying up of prime land, sorry to digress. No doubt I'm misguided, usually am.
Oh yes, I buy Famous Grouse whisky, love it.
