I've had a look through my bank statement for January, and what I've spent so far this month, as we did eat more convenience foods, e.g., takeaways, in January so it's not a typical month.
Including all pet food (7 animals), all food, toiletries, cleaning stuff, etc, for 2 older teens, my husband and myself we're averaging £171 per week atm. That would probably be much lower usually, but we ate a lot of sushi in January and it does include things like alcohol, a new pedal bin, etc.
I'd like to get it down to around £100 p.w., although apparently a budget of £5 per person per day is reasonable, which would be £140 p.w.
Even adding £10 p.w. for the animals still gives £150 p.w., which would mean I'm already not far off that, but it still seems like a lot to me.
