Since going broke a few years ago, I've discovered there are some things you just can't buy on the cheap. You just have to pay full price.
1. Toilet paper - Use your imagination. It's the difference between touching a feather and sandpaper.
2. Spam - I think Spam is actually pretty good. Imitation Spam is what people think of when they think of Spam; ugly meat with an unfamiliar and creepy taste. As bad as you think real spam might taste, imitation spam tastes worse.
3. Pop-Tarts - There are imitation Pop-Tarts that are okay, but the kind they sell at 99-cent stores are downright nasty.
4. Pens - Even if you do manage to find that pack of two hundred pens for ninety-nine cents, one hundred and ninety-nine of them will run out of ink and stop working within ten seconds.
This list could be longer, but I'm tired.
