Amazon, prices & links
Why don't I see a price on some products?
Amazon only lets us show a price that was checked in the last 24 hours. If our check is older, we hide it rather than show something wrong — click through to see today's price on Amazon.
Does Amazon pay you for good reviews?
No. As an Amazon Associate we earn a small commission when you buy through our links, whatever the score. Writers never see commission rates. Affiliate disclosure →
Do you sell mushrooms or kits yourselves?
No. We test products and link to Amazon UK. Orders, delivery and returns are handled by Amazon or the seller.
Saved list & compare
Where is my saved list stored?
In this browser only — no account. Clearing site data or switching device empties it. Use “Share list” on your saved page to move it.
How do I compare products?
Save them with ♥, open Saved, tick 2–3 products and press “Compare”.
Tools & calculators
How accurate is the yield estimator?
It's based on our own weighed grows, so treat it as a range, not a promise. Each tool page explains its formula.
Corrections & reviews
I found a mistake. How do I report it?
Use the correction form. Every fix is listed in our public corrections log.
Safety & the law
Can you identify a mushroom from my photo?
No — nobody should from a photo alone. Here's what to do instead →
Do you cover psilocybin mushrooms?
Only the science and UK law, in our ad-free Research & Safety zone. We never sell, link to or explain how to obtain or grow them.
Newsletter & your data
How do I unsubscribe?
Every email has a one-click unsubscribe link at the bottom. We never share your email.
Which cookies do you use?
Only essential ones until you choose. Analytics run only if you accept them in the cookie banner; you can change that any time via “Cookie settings” in the footer.
