Hello . I have just booked transportation service through Correos ( post office) . We are travelling from Santiago to Fisterre in five stages and the cost for this is 20 euros per rucksack ,or case. I organised this on line. The page was very easy to navigate . If you know where you are staying each night you can indicate or simply contact them each day before 21 .00 for collectionon the following day. They say the luggage will be collected after 8 in the morning and delivered by 14.30 at the Albergue ( or a central point if you are staying at a public Albergue) By the way we are beginning our Camino on June 5 th so haven't actually used the service as yet so I cannot comment on whether it is delivered as efficiently as it maintains on the website. Perhaps other pilgrims have used the service and can comment from actual experience. Buen Camino
