There is such an unforeseen circumstance as the Chinese New Year. Why it is such an unforeseen? Because every year comes at different times, roughly January - February. But every year the same situation is stable - 2 weeks before New Year factories begin to let employees go home, and after New Year, they're still come to sence one or two weeks. China does not produce goods about month per year. Don't forget that after the goods were produced, it still needs to be inspected and prepared by us, then send logistics and to your country. Considering all the facts, it is safe to say that during the Chinese New Year holidays it is worth buying goods in advance not to be left without them during the holidays. In our experience, the last purchase should be December 25. In such a volume that enough until spring.
