I can honestly say I've never bought a box of cigars.
I've bought plenty of bundles of 20 or more, but never a whole box at the same time of something good enough to actually package in a box. (bit of a cheapie aficionado here, in case you haven't figured that out :))
And I've paid a few bucks for _empty_ boxes at the B&M if they were particularly attractive, but I'm pretty sure that's not what you're talking about here :)
