The Best Way to Do that Bargin Shopping

I was just wondering if others are like me. When I go out general food shopping I get in the bargins regardless to whether I need them or not. I certainly now have a good stock of Kenco coffee Jars, various flavours from various countries, and also have enough shower gel to sort out the local football  team. 

Well not to be beaten by these superstores I was out again and managed to buy 3 large tins of dog food and at half price, yes that's half price, brilliant bargin and more stock to put in my ever growing cupboard, now all I need to do is actual get a dog.
