Same-Day Shipping Time
Same-day shipping refers to the time period in which we ship the order, not the delivery time.
Any orders placed before 12:00 noon, central time, (GMT -6) will be shipped out the same day.
Shipping time is then determined by the shipping service you select at checkout.

Shipping to someone else's address.
You can ship to any address, as long as your billing address is correct.
When you register your account, you will have an address book, in which you can store multiple addresses and ship to any one, at your choice.
Diode Dynamics has the right to hold any orders that are suspected of fraudulent activity.
Why hasn't my tracking number updated?
All U.S. customers, except in unusual circumstances, will receive a USPS confirmation number through e-mail. Please note that these are not tracking numbers, but confirmation numbers. We reccommend waiting at least 6 hours to check tracking information on your package. USPS confirmation numbers are updated at the discretion of USPS, and may not show update for some time after the order is shipped. Rest assured, your order is on the way!
International customers receive tracking for USPS Priority and USPS Express. USPS First Class International shipments receive an order identification number, and it is only very rarely scanned to show any progress. Usually, there will not be any update for international customers until the shipment passes into your country.
I have not received a tracking number.
Even if you have not received a tracking number, it is possible that your order has been shipped. Tracking numbers are sent by 8 PM every day.
Please allow normal processing time before inquiring about order status. This is usually 1 day.
For non-signature required shipments: If the tracking information that corresponds to a shipment confirms that the product was delivered to the intended address, the customer assumes all responsibilities and liabilities for the receipt of the shipment. The Customer is the one who provided Diode Dynamics with the ship to information, and in doing so absolves Diode Dynamics of any liabilities for missing or stolen deliveries.
If the address for the shipment was entered incorrectly and returned back to us, the customer assumes all responsibilities for the cost of reshipment.
