Huh Luxury!
Here in Spain we don't get a Saturday postal service never mind Sundays.
During the week there is a service but if the poor old posty gets tired he has a habit of dumping his remaining deliveries into whatever letter box he is close to when he feels a carajillo (coffee with cognac, anis etc) coming on!
DHL, a great company in the rest of the world tends to slow down here too, I just received a new phone from China, three days to get the several thousand miles from China to Palma Mallorca and three days to get the 80 odd miles from Palma to Ibiza.
