Both these books are doing well on Amazon.
Haven't bought them myself because I learnt thrift at my Cumbrian mother's knee. She was fearfully economical having been brought up during the last war and then marrying an Army officer who had to live on his meagre pay.
At one point my parents were allocated an unfurnished Army quarter/house and so were obliged to furnish it as cheaply as possible - they even bought a second-hand black carpet. Absolutely none of the little girls at my school had a black carpet in their sitting room, so I was mortified.
My main economy now: I don't spend much money on clothes because I am about to go on diet. Actually am always about to go on a diet - most Monday mornings, in fact. Like everybody else, I am cheese-paring about some things and extravagant about others. I spend money on heating because I like to be warm, but I can't bear it if somebody throws away the marmalade pot before it is finished, washed and recycled, or starts a new carton of OJ when there are three juices open already in the fridge etc etc. My mother was always saving dire left-overs in washed-out yoghurt pots and Flora cartons - she was far too thrifty to buy Tupperware - so you never knew which of these pots actually contained Flora and which would contain a sinister spoonful of ancient gravy.
I wrote an article about my mother's economies years ago and it went down a storm. People came up to me and said mine's just like that or even, I'm just like that. Clearly, she was ahead of her time as she was always green.
