I was at Uni for a few years on a budget with a family and found this helped.
Thermos flask, take your own coffee.
Water bottle, take your own drink and carry fruit or snack bar with you. Take a lunch everyday, you shouldn't need to spend any money at Uni. If you pay for parking find a street with no charges and try to get in there as much as you can. Drive slowly and freewheel down hills (be careful thought).
Bulk buy washing stuff when it's on offer. But a mooncup, £20 and no more need for tampons pads etc. it's a big monthly saving.
Stock up on cold and flu stuff when it's on offer (now). Supermarkets own brand. Get posh tissues when there on offer and save them for winter cold/flu bug blues to make you feel special.
Smart price cheese, pasta, pulses, sweets, all good. Buy meat when it's on it's last day and reduced, freeze it in portions. Use veg mince substitute from time to time it's cheap and goes a very long way. Use onions, carrots and other cheap veg to bulk out your food.
Soups, stews, pasta, curry, rice are your friends
.
Develop a baking cupboard and bake a treat cake each week, it's cheaper.
Save jars for homemade sauces and tubs for freezing things in. Any leftovers use or freeze.
Bulk cook food.
Treat yourself once a month. Something small if you can like a nice smelling bubble bath that you can use again and again and helps you relax.
Anything you dont spend save, you dont have to spend it cos its there. Good luck, it will be ok, it's only for a year and you'll be so healthy.
