I am currently in the middle of a two year cycling trip from Alaska to Argentina. As I write this I am in Yantolo and moving toward Cajamarca. I need to get some new tires and have not been able to find anything high quality here. I would like to ship some from either the US or Europe. Somebody told me that I may be able to ship to an Olva Couriers office, although I cannot find information about this on their website. I am wondering if anybody has shipped an international package to an Olva Couriers office and, if so, if there is anything special I need to know about how to address it? It would also be useful to know how long they will hold it for me.
