If you’re growing mushrooms regularly rather than as a one-off, buying single kits one at a time is the expensive way to do it. Our Buy 3 Get 1 Free bundles exist for exactly that situation – whether you want a rolling harvest, you’re stocking up for a group, or you’re buying kits as gifts for more than one person. Here’s exactly how the deal works, what counts toward it, and whether it’s worth it for what you’re planning.
How the deal works
Each Buy 3 Get 1 Free bundle is a single product listing built around one specific grow kit. Add it to your basket and you automatically get four kits for the price of three – there’s no discount code to remember and nothing extra to configure. The saving is already built into the price you see on the page.
What counts toward the deal
Each bundle applies to four units of the same kit – it’s not a mix-and-match discount across our whole range. If you want the deal on two different species or kit types, add the relevant bundle for each one to your basket separately; you’ll get the same 3-for-4 saving on each. This does mean the deal rewards committing to one kit at volume rather than sampling a bit of everything, which is worth knowing before you order.
Optional add-ons
Each bundle also offers optional add-ons at 10% off when purchased alongside it – things like nitrile gloves, a grow bag sealer, a GrowBuddie40 incubator, or a grow light. These are entirely optional and won’t affect the core 3-for-1 pricing on the kits themselves; they’re there if you’re setting up more than one grow at once and need the supporting kit to go with it.
Is it actually worth it?
Using the All-in-One Mushroom Grow Bag 1kg as an example, here’s what the saving looks like in practice:
| All-in-One Mushroom Grow Bag 1kg | |
|---|---|
| Single kit price | £9.99 each |
| 4 kits bought separately | £39.96 |
| Buy 3 Get 1 Free bundle price | £29.97 |
| You save | £9.99 (25%) – exactly one kit, free |
That works out to a genuine 25% saving versus buying four kits individually – effectively one full kit free – and the same ratio applies across all 16 bundles, scaled to that kit’s own price.
Who this is for
- A steady, ongoing harvest – buying four kits and staggering the start dates gives you a rolling supply rather than one big glut and then nothing
- Gifting to more than one person – four kits covers gifts for several people at once, at a lower cost per kit than buying them one at a time
- Schools, clubs and group projects – a group project needs multiple kits running at once, and the saving adds up fast across a full set
- Anyone growing to sell or share – if you’re growing at any kind of scale, buying in bundles rather than single units is the more cost-effective way to keep stock moving

Frequently asked questions
Can I mix different kit types and still get the deal?
Not within a single bundle listing – each bundle is built around one specific kit. Add a separate bundle for each kit type you want, and you’ll get the 3-for-4 saving on each one.
Do I need a discount code?
No. The saving is already reflected in the bundle’s listed price – just add it to your basket as normal.
Are the add-ons required to get the discount?
No, they’re entirely optional. The 3-for-4 kit pricing applies whether or not you add anything else to the bundle.
Can I buy more than one bundle of the same kit?
Yes – add multiple bundles of the same kit to your basket if you want more than four at once, each getting the same saving.
