Ranked from least to most frequent
  1. This seemed like your style.
  2. I saw this and thought of you.
  3. Happy <occasion>!
  4. I noticed you used <item> last time I was here, so I got a case of them in Costco.
  5. It's so unusual, right? I never saw anything like it.
    This is never a good thing.
  6. Everyone was grabbing them so I figured it was something good.
  7. You can always use an extra <item>!
  8. It was on sale for next to nothing.
    Sometimes followed by, "So even if you only use it once, it's no big deal."
  9. It's the hottest item. Costco (or QVC) was blowing them out.
