[Gocamino] Mailing to Santiago

[Glenn]

As I remember from my first Camino, the mailing address to send things ahead to Santiago From Spain was:
                                                         Name  + Peregrino  
                                                          Lista de Correos
                                                          15705 Santiago de Compostela
                                                          A Coruna
                                                          Espana.

Is it just as easy to send stuff ahead to this address from Bayonne or St. Jean PdP, France???  Do they have those convenient boxes one can buy in those French post offices?

I was considering taking some fresh clothes to France and sending them on ahead.  I didn't want to carry them across the Pyrenees.
