While we do our best to mail out all orders within 03 business days of that order being placed, there are various reasons why your order may be delayed or not shipped within that time frame. These reasons include, but are not limited to, the following: - Items are out of stock - Items are pre-order - A significant release or holiday period has created a large influx of orders (expect processing/shipment to happen within 2 - 4 business days during these periods) In the event of an item being ordered that is not in stock, we will contact you, letting you know of the delay and the expected shipping date. In ordering an item that is considered "pre-order", the expected ship date of the product will be listed on the product page at the time of ordering. Please keep in mind that your order will ship in full once all items are available for shipment in both of the above cases.  Any questions or concerns related to a delayed order, please email us at info@maztermind.vn and reference your order number in the email subject line.
