A missed opportunity
Some carriers don't have what the Post Office has ... namely a high street presence. I believe there is an opportunity for "shops" that represent various couriers and customers can drop off parcels and possibly collect as well, where it is impractical to either have things sent to work, or take yet another day off work for a courier to turn up at home.
Right now, I've got to organise a parcel to Germany, which Parcel Farce will want three digits of notes for. However, to deal with the other guys, they're going ot have to pick up from premises, and that could get awkward with my employer ... potentially.
One "shop" can actually represent multiple couriers. Split costs, and all that. Do the paperwork on-line even and just drop it off.
