Merchants are right, because diamonds are not like clothes. There are only a few specifications. Diamonds with different weights need different grades, from 20-point D/IF to I/P, and then to 2-carat D/IF to I/P. If all merchants stock up, how many goods do they have to buy? Interviewee: fanfanrr has a mental problem. Diamonds alone need so much, not including other finished jewelry. How can you ask the merchants? For example, Beijing is dominated by high cleanliness, so it is dominated by high cleanliness. If the customer refuses to buy this product, it will be out of stock. What if the customer doesn't want the goods that the merchant has tried his best to order? Because ordering by merchants is equivalent to asking suppliers to buy goods, some merchants need a deposit to buy goods. If the customer doesn't want it, the merchant has already put the goods in his hand. what should he do ？ If one or two customers are so good, there will be more people. This method is feasible. 20 customers want to buy it, but they don't want it when the goods arrive. Don't talk nonsense when answering questions in the future. E-commerce has advantages, but it mainly depends on manifests. Small diamonds are asked everywhere if they are borrowed, but if I want 10 carat, the stock is usually very small, so e-commerce suppliers will have to transfer goods from abroad. In this case, I say this because the defendant: fanfanrr, has never encountered such a problem. If you are a jewelry colleague, your position is too low, so you don't need to consider this issue. I hope to answer the question seriously in the future, but I heard the second half of the questioner: How can I introduce the advantages of our e-commerce in the face of such customers? The advantages of zero inventory and 20% deposit, I think the questioner is also a jewelry colleague, hehe, I hope my answer is helpful to you and I wish you a prosperous business.
