Where have you needed this? Will add it to our expansion roadmap! Keep a look out for us next time. We're in 72 cities now and that number will at least double this year.
I have a room full with crap; even at $1/day per case (which I would pay long term), I can put enough cases in there and easily get them out to pay triple the mortgage on the entire house every month... All my chinese and thai friends (where I store stuff now) would gladly long term store cases in their houses: 20-30 of them for sure.
Short term they would not but 2 weeks or more; many people working abroad would jump at that.
Seems I always forget something or forget to bring it home. Would be nice just to not stress about them during packing and just focus on clothes laptop etc
I don't keep dupes of everything. My cables and plugs bag is the same one I use day-to-day. But I do keep a general travel pile that has most of the stuff I may need on a trip other than clothing--which varies by location/season/type of trip.
At least that's what I used to do.
