I’ve been quietly gatekeeping this, but if you’re in France in January or July, it’s impossible to miss. Every shop window, from luxury boutiques to high-street chains, is plastered with the same word in bold letters: SOLDES.

To anyone visiting from outside France, it looks like a normal sale season. It’s not.

Les Soldes are a legally regulated national retail event, with fixed dates and strict rules. This is not just a marketing moment. It’s a very specific system.

So… what is Les Soldes?

In France, retailers are only allowed to run official Soldes twice a year:

• Winter Soldes (January–February)

• Summer Soldes (June–July)

These dates are set nationally. Retailers do not choose them, extend them, or move them around. When the window opens, it opens for everyone. When it closes, it closes for everyone.

As a digital nomad, I’m also very aware of what I buy. I don’t have closets or storage space spread across multiple rooms. Everything I buy has to earn its place. That usually means I’m drawn to pieces that are well-made, versatile, and a little bit interesting, things that let me keep a personal style without defaulting to the same black jeans and plain t-shirts everywhere I go.

So on a rainy afternoon in London, the last time I visited, I walked into a charity shop and found a well-fitted tweed blazer. It fit properly, felt high quality, and worked with the rest of my very limited wardrobe. The find itself was luck, but the conditions that make moments like that possible are very predictable in a retail culture where second-hand shopping is normalized and accessible.

Charity shops and second-hand retail stores aren’t just a trend or a sustainability talking point. They represent a functioning circular supply chain operating at scale, in plain sight.

When companies talk about “cutting logistics costs,” the conversation almost always goes straight to rates. But for most businesses, the real money leaks are not from rates, they’re buried in timing, processes, and people's decisions that quietly add cost every single day.
