The price of things

We were at the grocery store yesterday, and just as it was our turn to check out, I realised I ought to get a new toothbrush. So I hollered to T to grab me one ("preferably pink!") and whatever he came back with, I just tossed it into the pile of groceries being rung up.

$6.66 for a toothbrush?!

Admittedly, I hadn't changed my toothbrush in a longer time than even the most forgiving dentist would consider hygienic. But when did toothbrushes become that expensive? When I looked at the description on the packaging later, it sounded to me like my new toothbrush had the bristles you'd expect of any ordinary toothbrush, and not much else. The description also observed that dentists recommend changing one's toothbrush once every three months.

At $6.66 a pop?!
