The customers of Wickes and B&Q are most likely to be sub-urban dwellers and not farmers, but in terms of the impact, I think this is huge. Are Wickes and B&Q discontinuing sales because of their environmental beliefs? I doubt it! It's much more likely they stopped selling the products because their customers don't want to buy them. I'd bet it is a purely commercial decision; they are simply no longer making profit from them. But hats off to the environmental lobby for making them commercially non-viable in the domestic environment!
All we need now is the major agricultural wholesalers and distributors to follow suit.
