In reply to Cheese Monkey:
It's a pain in the bum that will only be resolved by having good neighbours.
We used to live at 21 crossflatts parade and regularly got mail and packages for 21 crossflatts Street and Grove.
The only thing to do was deliver it between our selves.
We all made complaints at the local sorting office but for some reason we seemed to be the area that got all the temporary and relief staff.
After a few years we got a permanent guy and he was great, he even dropped parcels off on his way home as he passed our house. Always gave him a good tip.
