We have encountered an huge volume of orders last weekend ( May 13th ~ May 15th)
So, your order might take a bit longer (3~4 more business days) to be shipped.
We will email you as soon as the item in your order shipped, or you can check it on order status.
However, your updated tracking number would not be actually traceable a few days after you get your tracking number, since we are planning to send them to the post office or FedEx altogether when a certain amounts are reached.
Sorry about the delayed shipping, we will try as hard as possible. (We are currently working 9am to 11 PM)
and our current estimate is that we will ship all orders within 3~4 business days (by Thursday, May 19th) after your order has placed.
