Someone I know almost came to blows in Asda, when someone tried to pinch the pork joint out of her trolley. She said she saw her the following week, so took great delight in telling her the pork had been lovely.. big laugh
I never go to the sales intentionally to "bag a bargain", most of the deductions aren't what they seem anyway. We laugh at the furniture stores having all year sales, but they all do it so there are bargains to be found at any time of the year, and you can do your research online from the comfort of your armchair.
