Video contains throwing of cups and rude language. Down with that sort of thing! Careful now!
The big red book contains the story of my spending life, the small book is the grocery spend (the nail file is an excellent bookmark), the piece of paper is a kind of shopping list.
Things are divided up into assorted sections, I made them up as they suited me at the time. I keep a tally chart to remind me of quantities
Then I keep a note of how much I spent on each item
At the end of each month I add it all up!
My categories are -
cleaning/household basics (includes pet food)
books, magazines etc
car (not including fuel)
misc (inc parking)
And that's it.
