Dangdang and Zhuoyue have great advantages in purchasing books (such as audio-visual products), because basically every place has its own warehousing and logistics, with low distribution cost and large coverage. There are many kinds of books, which are popular and suitable, and can meet the needs of most people. But it can't compete with the first three websites in other commodities. The security is also good. Payment methods are now more convenient for any website and banks are more complete. Now these two websites extend the advantages of warehousing and logistics to other commodities, so many people are willing to spend more money on other commodities, such as cosmetics and daily necessities. These two websites also have advantages in after-sales service.
So it depends on what goods you want to buy and at what price.
