Buy in Bulk
If you live in shared accommodation, think about having an arrangement with your flatmates so you can all save a bit of money when it comes to shopping for the flat.
Buying in bulk is often cheaper, so if you pool your cash for certain items, it could knock a big chunk off your weekly bill.
For example, buying toilet paper in bulk and splitting the cost between a number of people is way more effective than if you all individually buy a two roll pack every other day (what even is the point in two-roll packs?).
Make sure you always do the math before buying in bulk though, as sometimes you’ll find that you’re not actually getting a better deal – despite what the supermarket would like you to think. Sometimes a deal is not a deal...
