Ours, In Norwich, does that too. But they wouldn`t deliver to our particular site for years because they said they couldn`t get the trucks through the gate.
Then a couple of weeks ago I spotted a work gang taking away the leaves near our site that I was going to get myself. I spoke to the driver and he agreed to give it a try...The drivers of the smaller trucks are now delivering to us too so now we have all the leaves we could ever use. So that shows its always worth asking. ;D
