Where do you store your extra blades?

In a wood tea box, along with most of my small cream and cologne samples. Of course, I only have about 100 blades at the moment.

Wherever SWMBO tells me to.

I've got a few packs (in use) in the medicine cabinet, and the rest are with my spare soaps, in a ziploc bag in a cabinet under the shelf where I "display" all my other shave den gear.
