Is my inflation worse than homes like mine? What do people really pay for my staples? Which money-saving swaps actually stuck? Are my "weird" habits secretly common? Which items only ever sell on offer? What's my most expensive habit? When do I really start Christmas shopping? What did my first-ever basket say about me? Which two items never shop apart? What's the one thing I always forget? Did January's health kick survive to March? What would ditching the meal deal save? Settle it: who's right about the biscuits? My 2019 shop at today's prices? Is the delivery pass worth it?

We want you to get as much value from your own data as the retail industry already gets from it.

We are not a data business: we don't and will never sell your data. We store it safely and have developed the tools to help you understand what it's saying. It's yours, and we only ever show it to you.

We don't host adverts or have sponsored content. If we tell you something, it's always our impartial view based on facts.

So yes, we've switched sides of the counter. For decades the data has flowed one way: from your basket to the supermarkets. Cannie puts it back in your hands.
