I have a couple of pouches that I keep filled in case I find myself with the time/opportunity to visit my preferred B&M. Since I prefer to smoke only tobacco that I bought there, I keep one pouch filled with "Victorian Standard" (which is the name they put on Lane's 1Q) and the other pouch with something else purchased there (currently either Frog Morton or FM Across the Pond).
At work, I keep a couple of cobs for lunchtime lunting. I usually move one of my small 'sample' jars to the desk to finish off the last of a tin or a sample (right now, I'm working through some McClelland's #1 Grade Balkan), but I've picked up yet another pouch that I carry along just in case I burn through the first bowl quicker than expected - right now, it's got the last of my Prince Albert pouch, but I've got a jar of Sugar Barrel waiting to refill it. I'll probably switch off between PA and Sugar Barrel in that pouch, as they're both becoming favorites.
