<prompt> Human: First time posting in personal finance but Ive decided I need to sort out my finances a lot better than I do at the moment.I live in the UK and I moved job about a year ago basic warehouse work to a new company and I got a wage rise with more hours a week also and in this job I can do over time at time and a half so my hourly rate plus half of that on top. I have also been promoted to a stock controller role which also boosted my income.Having said all this my partner asks me where does all my money go, so I sat down and added up the total amount of trips to supermarket every other day and the value of it and worked out over 400! That is for me and my partner at night since she currently stays at home with her parents so isnt in the house eating while I work, that being said I get my son two weekends a month and spend a bit extra on food for him. But nonetheless I was shocked that I was spending that amount solely on juice, food to take to work, and dinners.So I decided what if I cut that to 250 a month at the start of the month and take out the cash and put the bank card aside and I done a Google sheets and it worked out I will save 220 a month just by doing that and putting 100 aside for petrol. This includes all my mortgage and house hold bills and phone bill along with gym and Netflix etc.So in a year not including any over time and not including my new salary i will be on shortly I will save 2650 a year just by doing more big shops using cash than little every day shops and adding in more junk that I dont actually need. If anyone has any other tips on saving monthly I would appreciate hearing them as i have two 0 credit cards I owe about 2000 to which I really want to pay off even tho I have about 3 years to pay it off  <response>: Meal planning is a huge help when trying to save money. It requires some work up front, but with some time and perhaps a crockpotslow cooker youre all set! There are a lot of websites if you search online that can help with weekly menus and ways to shave costs off your food budget.
