I usually keep 1/8th - 1/4 ounce per week for personal stash (assuming I haven't been growing), and I smoke top notch bud from cali - like purple kush, ak47, afghan trainwreck. Anyways that bud really stanks when you're trafficing, so I normally take a fresh tupperware when picking up. I have a stash spot where I can put the tupperware under my console easily, centrally located. I dunno why, but my console just comes apart like that and I can lift it up and stash underneath.
At home, I usually have no reason to hide it so it sits on my tray in a drawer with my pipes and papers, ready to be rolled up. But, if I need to hide it at home, I hide it on the top shelf of my closet, in a tall snow boot that I never wear (yes it's clean). I can fit probably up to 4 ounces if I stashed in both boots, and I usually shove a clean sock over the top of the boot to cover, so the bag and smell is more concealed. I also put my mason jars up on that top shelf when I'm curing buds since it's a nice cool dark spot. But like I said, I normally am not hiding it from anyone.
