I have a friend who has mastered the art of 'two for one' shopping. She reminds me of my old Gran who would walk from shop to shop looking to save a few pennies here and a few pennies there. Anyway, my friend Norma works a 'team shopping' system, where she and a buddy shop at various supermarkets, focusing on special offers and 'two for one' deals. She tells me that doing this, they were able to save enough money for a nice holiday in the Canary Islands, although the price was eating a lot of pizza and brains faggots. Sorry, forgot to mention - they share the shopping and sometimes end up with a complete trolly full of free food.
