As I'm a SAHM, I usually end up taking in the neighbour's parcels for them as I'm the only person who answered the door to the delivery company.
Most of the neighbours will call round later that day or the next for their stuff.
One chap, who lives about 5 doors away, never does. It's always too big or awkward for me to take round while also carrying DS2 or pushing his pushchair, especially knowing that I might have to lug it back again.
His latest parcel is flat, about 1 foot wide and 5 feet long. He apparently paid extra for next day delivery, but obviously doesn't want it that urgently as it's been in my house over a week.
I probably won't put it out with the bins, unless it's here another week, but won't be taking in any more parcels for him.
