Found this in my local Wilkos in Melton. Growing success slug killer 575g for just 10p. I took the last two but the assistant said they are reduced to clear as Wilkos will no longer be stocking it. I have no idea if it’s national, but surely worth a look if you’re going into your local store. The link takes you to Wilkos site. They still sell it online for £7. This will come in very handy down the allotment.
