I went shopping this week to get a few necessities and one of the items on my list was a box of razor heads. Not remembering the word for razor heads (probably because, who uses that in every day conversation?? Not me apparently), I pointed at the box of 3 and asked to buy it. The woman nodded, pulled out a single razor head and proceeded to ring up my total. I went along with it since, who needs 2 extra razor heads just sitting around? Plus, it reminded me that one can buy a select amount of just about anything that comes in a package, something I have found to be both interesting and efficient. You want 10 diapers? Sure. You need 3 cigarettes? Done. Five ballpoint pens? You got it. And apparently it applies to razor heads too.
