Diyweek.net's recent coverage of council 'sting' operations has led to scores of retailers getting in touch to say the system is still unfair.
All agree the law on age restricted products needs to be enforced, but DIY storeowners are still saying they're not getting any information from their local trading standards department.
That is, at least, not until they're caught out in the entrapment-style system currently used to monitor under age sales.
In DIY Week, out tomorrow (Friday 20 March), we speak to one trader, Jim Turner owner of Portwood Supplies in South Norwood, south London, who faces court after being 'stung' to explain the process for the retailer.
We also hear from a trading standards officer about how they target particular areas and the methods they use.
DIY Week also outlines the exact information retailers need to know to stay up-to-date with the law in a 'cut out and keep' guide to age-restricted sales.
