Somehow My Math Brain Wasn't Kicking In
Hmmmm. Bought three ink cartridges for my printer at a yard sale a few weeks back. They were long past their expiration date but I figured it was worth a try at two bucks each. In the store they run $30 each. I figure if they work, it's a bargain. If not, I haven't lost a great fortune.
I don't know how many prints I can get out of a NEW cartridge. I know it's a lot but I've never counted them.
But out of curiosity I decided to count the prints from the first of the $2 "bargains". So I kept a running tally.
Today's copy count approached 750 and I was jumping up and down with excitement. Bragged on Twitter. That was not wise. Ten sheets later the cartridge ran out of ink! I took the cartridge out, tapped it on the table top sidesways, upside down, right sight up. Tap! Tap! Tap! TAP!!! The printer hiccuped and gave me a couple more copies that were a bit on the unacceptable side.
Still...760 prints at $2 makes my per copy cost at about one-fourth of a penny per copy. Not bad. Even if the two remaining cartridges are dead from the get-go, I've still had a good run. And hey, when the three cartridges are used up, I can trade them in at my office supply store for a $3 credit each. That is a $1 profit above and beyond all the printing.
But I'm not so smart after all. There were several other cartridges that she was selling at $2 apiece. Could have traded them in for $3, too.
I'm laughing (at myself) all the way to the kitchen for a cup of coffee.
