What's an impulse buy you actually don't regret at all?

A natural way to answer

I'd say a small coffee machine I bought without really planning to. It seemed like an extravagance at the time, but it's earned its place. Some impulse buys genuinely pay for themselves over time.

Key phrases to use

• on a whim — suddenly, because you feel like it, without planning“We booked the trip on a whim.”
• paid off — to bring a good result that made it worthwhile“Taking the risk really paid off.”
• pay for themselves — to save or earn back enough money to cover their cost“The solar panels paid for themselves in a few years.”
