Avocados, Jack, there's no E (pedantic I know, but that's the UK English spelling, plus I can't help myself). I know you're a "writer" but if you need an editor, loads of people on here can help. YW
Apples 65p? Really? Where? Is that for 2, or the end of the Aldi aisle where the cheapo range is?
Instant mash 80p - you have a cooker and hob, far cheaper making your own. People who can't afford to put their cookers on, fair enough, but you CAN put yours on to use a bit of gas or electric. Bag of potatoes - much cheaper. There's a tip for ya Jack!
Also, instead of not spending 55p on dishcloths, make your own. Aren't you always preaching about being resourceful? (Or maybe I'm thinking of someone else with a bit more intelligence...)
