To Know



Free shipping on Most Orders          

We ship through UPS standard ground and USPS for fast and reliable shipping. We even provide free shipping for most orders. (Not including Hawaii, Alaska, and Puerto Rico and international countries) Orders received before 3pm PST are shipped the SAME Day. Please note UPS ground/Standard does not deliver on Saturday, Sunday, or holidays. USPS will not deliver on national holidays and on Sundays.


We ship through USPS Express mail for international countries. The reason is that Seller/Buyer/ Tracking company could track tracking number of package although the package is out of Unite State. Please contact us first before purchase and ask for right rate of international shipping.


Track Your Package

Once your order has been shipped, you will receive a confirmation email with your tracking number and links to track your order on-line with UPS or USPS. Again, we cannot guarantee UPS/USPS delivery times as the delivery time we receive from UPS and USPS are approximations.Once the package leaves our warehouse and has been scanned into the UPS/USPS tracking system, we will do all we can to ensure that it arrives without unnecessary delay. However, TNT Electron cannot be held responsible for any unforeseen and unavoidable delay while the package is in the care of UPS/USPS. Also, it is the customer's responsibility to provide the correct shipping address. To prevent delay or possibly even extra fees, please provide us with your correct and current address. If there is an address change while the package is on route, we cannot take responsibility if the package is lost or if UPS charges the customer an extra fee.The UPS driver or the USPS delivery person at his or her discretion may choose to leave the package at the door. TNT Electron cannot take responsibility for packages that are damaged, lost, or stolen after it has been delivered. We strongly recommend that the customer track package frequently and that there be someone to receive the package when it arrives.
