Trekking and sending luggage home
 

We're going to be trekking in Patagonia in early 2019 as part of a much longer trip to South America (maybe 2 months). We think it would be best if we pack all our hiking gear in one duffel bag and send it home once we're done with it. Has anyone ever done this? Via what service did you send it home? Do you remember what it cost?
