Hi. My husband and I will be walking from Le Puy to Santiago de Compostella (and likely on to Finisterre, though I haven’t mentioned that part to my husband yet). There are a few things (including medication refills) we would like to post to ourselves in St Jean PDP and then again in Santiago. We have no idea how long we will take to do our walk this time, and we hope to not book anything much in advance as a result. Is there a service that will store packages for several weeks, in SJPDP and Santiago, or is there one that will post prepared packages within France or Spain when asked to? We had a friend that used to live in Barcelona, and last time we sent our three little pre-prepared, unaddressed packages to him to be sent to addresses we advised him of, a few days before we needed them. That is exactly what we need again, but our friend no longer lives in Spain. Any ideas would be appreciated.
