Q: How long could it take to receive a product from the time it is ordered?

A: We encourage customers to plan ahead to allow extra lead time for their products to be delivered. The length of these delays vary from product to product on a daily basis but fulfillment delays for some products have recently been around 4 to 6 months.

自己说要expect 4-6个月，那么1年也属于可能范围之内了。这个是很头疼的。
