I wonder if Dangdang's business model is the same as eBay and Taobao?

Ebay and Taobao are both CtoC models, that is, they only provide platforms, and the people who really sell things on them are individuals. Be sure to see the reputation and payment method clearly, and ask after-sales questions such as the warranty of large products to avoid unexpected disputes after the transaction.

Excellence and Dangdang are both BtoC models, that is, in the face of their own consumer operations, word of mouth and quality are more guaranteed. But some cosmetics are also outsourced to other partners (such as the rental counter in the shopping mall), so we should also look at it clearly.

Friendly reminder: online shopping must depend on whether this website is formal, whether it has ICP certificate, red shield sign for industrial and commercial record, and whether it supports cash on delivery. There are many online scammers now, so don't believe it easily because of the low price, hehe. It is best to choose cash on delivery for the first transaction. If not, you should also use third-party payment tools such as Alipay and Tenpay.

Generally speaking, BtoC's website has a higher safety factor than CtoC's.
