Also applicable to shoes/clothing. If you find a great sale on an expensive brand and item you know you’ll always wear and is a pretty timeless style, double down if you can.

For example, I always wear Red Wing boots. They’re expensive but generally worth it in my opinion; they will always be useful to have, last a long time, and the basic styles won’t expire. There was a shoe store going out of business and was selling them for more than half off. I bought two pairs and rotate them each year. Now I have boots that will last me for more than a decade and only essentially paid for less than one pair. This holds true for other items like quality jeans, sport coats, etc.
