Decathlon is an expansion of Auchan, a French equivalent of Walmart and the competitor of Carrefour.
They usually use their huge purchasing power to force top vendors to sell them under their Decathlon brand rather good products at highly discounted price and pass it to customer.
In a few year, they took over the French sport equipment market.
The good news is the price. The bad is that you can kiss goodbye to product diversity: they kill everything else. As if Walmart was selling primarily a few Walmart branded products.
