Quick answer: The big supermarket spice brands have a wide range and shelf presence in almost every store. Costack is a direct-to-door UK seasoning brand built around bolder, pre-blended mixes. Choose a supermarket brand for convenience and single spices. Choose Costack for stronger ready-made blends delivered to your door.
Two different jobs
Supermarket spice brands and Costack are often compared, but they are built for slightly different shoppers.
The established supermarket brands win on reach. You can pick up a jar on almost any UK supermarket trip, and the range covers single spices, herbs and blends.
Costack is a UK seasoning brand focused on pre-blended mixes for everyday cooking, sold direct from costack.uk and delivered across the UK. The focus is fewer products, each one a finished blend, built with care.
Neither is simply better. They suit different needs.

When a supermarket brand makes more sense
Pick a supermarket brand if you want to grab a jar mid-shop without planning ahead, if you need a single spice such as cinnamon or paprika on its own, or if you prefer buying a name you already recognise from the shelf. Supermarket availability is a real advantage. There is no delivery to wait for.
When Costack makes more sense
Pick Costack if you want finished blends that do the thinking for you, if you want stronger flavour from each spoonful, or if you care about a clean label and a focused range.
The direct model also means the blends are bought fresh rather than sitting in a warehouse and on a shelf for months. For cooks who season every meal, ordering a few blends or a multi-pack at once removes the mid-week supermarket trip.
Frequently asked questions
Is Costack cheaper than the supermarket brands?
It depends on the product. Costack everyday blends start at ยฃ2.99. Pricing shifts on both sides, so compare the current price per jar and the price per use, not just the headline number.
Can I buy Costack in supermarkets?
Costack is sold direct from costack.uk and delivered across the UK. A supermarket brand is the one to reach for if in-store buying is the priority.
How do the brands compare on ingredients?
It varies by product. Some blends rely on flavour enhancers, others rely on whole spices. Check the label. Costack delivers premium spices and seasonings.
Which is better for ready-made blends?
Costack is built around finished blends, so each jar is a complete seasoning. The supermarket brands offer blends too, alongside a much larger catalogue of single spices.
Which should a new cook start with?
A new cook usually gets further faster with finished blends, because there is less guesswork. A Costack starter multi-pack covers most everyday cooking from one order.
The verdict
The supermarket brands win on reach and the sheer size of their range. Costack wins on bold, finished blends with a clean label, delivered to the door. Many UK kitchens end up with both: single spices from the supermarket, and a shelf of strong ready-made blends for the cooking they do every day.
