I sent and received parcels by bus. A very good price tag for delivery even for large shipments (I sent both 10 and 20 kg each). Compared to large delivery services, it is very profitable. The timing is also quite adequate - on average 2-3 days. Sometimes it is delayed up to 4-5, but taking into account the price, it is not critical. There have never been any problems with the safety of parcels, everything arrives safely.
