The comparison study was carried out as students head to university this September

The study was carried out as students head back to university, many of which will be looking for ways to save on their weekly shop. Additional research commissioned by shows that, although 95% of university students agree buying in bulk saves them money, they still admit to buying individual items. Single bars of chocolate and confectionery are bought most often by students at 1.6 times per week, and with the possibility of saving 45% on Dairy Milk, it seems some could be missing a trick. 

When it comes to buying multipacks and in bulk, over one in five students (21%) say they would buy multipack items more often if they had more space available.

A shocking 95,200 students didn’t know you could buy multi-pack items.   

Anita Naik, Lifestyle Editor at, commented: “When going around the supermarket it can be easy just to pick up the things you need to cook for that day or for a specific meal, especially if you’re only cooking for a small group. But actually, our research shows that over time there are big savings to be made if you buy bigger pack items to last you a few meals.

“Creating a meal plan and shopping list ahead of visiting the supermarket will help you plan ahead and budget accordingly. When doing your food shop make sure you look out for multipack deals. Check the label to find out the price per 100g and compare multipacks against individual items to give you a better idea of value for money.
