How you save big with Bunsen

What suppliers don’t want you to know 👀

Supplier prices vary so much these days.

One reason is that it’s difficult to compare prices: you’ve got to flick through catalogues or visit supplier sites one by one.

Sometimes it’s just not worth the effort 😪

Suppliers know this and get away with charging higher prices on some products and lower prices on others, because it’s so slow to shop around 🐌

And even though some suppliers say that they’re wallet-friendly, no single supplier offers the lowest prices across all products

This means that the market isn’t transparent - and it’s schools that lose out.

We’re on a mission to fix this 🚀

Why we’re building Bunsen 🛠️

You use Google Shopping, MoneySupermarket and CompareTheMarket to compare prices when buying things for yourself.

So why isn't there a price comparison site for school supplies, especially as budgets are tightening?

That's why we've built Bunsen.

We let you compare prices from all your favourite suppliers on a single site.

This makes the market more transparent, and saves you money.



We’re the secret that suppliers don’t want you to know about 😉

Let’s see how you can save 30% on a typical shop for your school 💸

We've designed an example basket with products that schools often buy. The basket contains a mix of

🧪 Consumables

🫗 Glassware

🔬 Big, one-off purchases

We also account for the fact that schools buy different items in different quantities.

Here’s our typical basket.
