20 days ago, I had sent more than 30 styls of our products to the client who we had not make business before.Several days before, I sent the email to him and he reply that they had check the price and quality. Until now, they do not send any news to me. I feel puzzled. What should I do? Are they samples hunter? As a saler in Internet, I always can not distinguish true or not. Pls, give me some suggestion. Thanks.
