Why do people prefer Aldi?

Why do so many people prefer shopping at Aldi over other grocery stores? Is it simply because of the low prices or are there other factors at play? Does Aldi's private label brand offer comparable quality to name-brand products? How does Aldi's no-frills approach to retailing affect their customer base? And how does Aldi manage to keep their prices so low, even with the rising cost of goods? Is it their efficient supply chain or their unique business model? It would be interesting to explore these questions and understand the driving forces behind Aldi's popularity.
