I tried rum in a box. It didn't end well.
And recently I worked with a young programmer who told us in a meeting how she and her college room mates used to remove the bladder from the box and toss it around the room. Whatever interest was left flew out the window.
Yeah, I've seen rub in boxes too down in Colombia. Some of the boxes were small like the size of a children's juice box.
The spices is a good topic. One thought I've had myself is if I were to use a lot of a certain spice, I'd get a bunch of the smaller kinds. that way, a large container doesn't go bad so quickly. Just pack them in a way that they don't move around too much, and I'm sure they'd last.
