Affiliate disclosure
Plain English: some links on this site pay us a commission if you buy.
DupeStack is a participant in the Amazon EU Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk and other Amazon EU sites.
Our Amazon Associates tracking ID is dupestack-21. Product, sprayer and PPE links in DIY stacks typically include that tag. We may also join other affiliate networks later; this page will be updated if we do.
Commissions do not change listed concentrations, CAS numbers, dilution ratios or the calculator output. Prices shown on DupeStack are indicative seed figures unless stated otherwise — always check the live price on the merchant’s page.
As an Amazon Associate we earn from qualifying purchases. For ASA/CAP purposes, treat DIY-stack buttons and product links as advertisements.
Handling concentrated chemicals is on you. Read the SDS, wear the stated PPE, and follow UK HSE and COSHH rules. See also our privacy policy and contact page.
