Ok so last month I kept every receipt and kept a record of everything we spent, right down to parking tickets. I'm pretty shocked at how much it all comes to particularly as we made a conscious effort to stop frittering away money.
I meal planned and made sure I only do one big shop a week as I knew I was spending too much in supermarkets, have stopped buying takeaways, going to coffee shops so regularly, stopped buying the dc's endless "little treats" that add up considerably and have basically stayed away from browsing around town.
I never kept records of all our spending beforehand so I don't know how much we've improved but I know that we were spending around £100 a month on take away/coffees out etc, plus treats here and there, new clothes etc etc.
Anyway here is September spend, please help me get it even lower!
