The Western Box is en route to the Bay Area. My hiking buddy and I took several things, and replaced with lots of high value and fun items. We helped ourselves to an MSR water filter, fleece jacket, walkie-talkies, sun/rain hat, a few very small containers, Frog Togs, and a pair of looong merino blend socks. Our contributions far exceeded in monetary value what we took out.
The box currently weighs 21+ lbs and cost $31 to ship Seattle > Bay Area (the previous shipper paid $18 to get it to me from Corvallis, OR). I had to really strap it together with packing tape; it may be time for a new box, unless a bunch of big stuff is removed. We added as much as we possibly could, at least 20 items!
The sheer number of items and cubic volume of gear required creative re-packing/nesting/filling all dead space. So be sure to open EVERYTHING up and look inside if you don't want to miss anything. I carefully packed items into every nook and cranny I could find.
