Heh. Apparently these are "free with purchase." Heck, if you want dust bunnies, feel free to stop by my place, and you can have as many dust bunnies as you feel like collecting, no purchase necessary.
I *really* need to do something about the roaming herds of dust bunnies (or are they now dust bison?) in my apartment. I sure wish I could figure out where my swiffer duster wandered off too... the dust bunnies are thick enough that the duster might work better than the sweeper, at least for an initial pass. *sigh*
