Why use Voucher Magpie?
Every Costack Spices deal here comes from Costack Spices itself or its official affiliate programme, never copied from another voucher site. When you shop through our links, Costack Spices may pay us a commission. It never changes your price. We give 50% of that commission to the charity, club or school you choose, at no extra cost to you.
About Costack Spices
Costack Spices is a seasoning brand based in Manchester, run by Costack UK Ltd, a company registered in November 2014. Its founder, Fred, started the business to offer bold spice blends that he felt were hard to find without a trip to a specialist shop, and he still signs off the website's founder notes himself. The company also lists sister businesses in the United States, South Africa and Tanzania.
The range is 19 blends and single spices. They include everyday seasonings such as Complete Seasoning, All Purpose Seasoning and Chicken and Turkey, plus West African and global flavours such as Smoky Tomato (Jollof) Rice Seasoning, Suya Spice, Cameroon Pepper, Adobo and Smoky Peanut BBQ Rub, and stock powders. Some savoury blends contain flavour enhancers such as MSG, which the site states openly; single spices like garlic granules and ground ginger have nothing added. Each product page lists the heat level and allergens.
You can buy single jars and sachets, ready-made bundles such as The Essential Refill (£10.97 for three best-sellers), a build-your-own box, monthly subscription boxes and a recipe ebook. UK delivery is free over £35, orders are processed within one to two working days, and Costack also ships to the EU and further afield at flat rates.

Can I use a Costack Spices discount code on sale items?
It depends on the code. Many discount codes exclude items that are already reduced, so open Terms on the code before you use it.
Why didn't my Costack Spices code work?
Most codes exclude gift cards and items already reduced, and some need a minimum spend or are for new customers only. Open Terms on the code, or tap "Didn't work?" and we'll recheck it.
Are these Costack Spices codes verified?
Every Costack Spices code here comes from Costack Spices itself: its own daily feed through its official affiliate programme, or its own website. Each offer shows when we last checked it.
Does Voucher Magpie donate to charity?
Yes. When you buy from Costack Spices through our links, Costack Spices pays us a commission, and we give 50% of it to the charity or club you choose. We pay each cause its confirmed commission every quarter (Jan, Apr, Jul, Oct), once the shop has confirmed the sale, usually 30 to 90 days after the order. Minimum £25; anything under that rolls over to the next quarter.
Does using Voucher Magpie cost more?
No. You pay Costack Spices' normal price, less any discount. Our commission is paid by Costack Spices or its affiliate network, not by you.
