Costco: Buy now ?

$COST (-1.09%) is similar to $WMT (-2.1%) is a real heavyweight in the retail sector and is known for its blatant business model: customers pay a membership to get low prices. As a normal consumer in Germany, I've never seen that before. This not only creates a strong bond with the customer, but also ensures stable and regular income. Costco remains strong, especially in uncertain times, because they have their costs under control and still offer good prices. Sure, the share is not cheap or has already risen very sharply, but good companies cost their price, don't they? In addition, there are good quarterly figures and solid growth, which could drive the share price further in the future. But there are few dividends. What do you think: should we get in?
