If tracking shows following 3 conditions, it might be held by your customs for checking.
1. still in Taiwan (TAIPEI INT AMF, TAIWAN)
2. not moving at e.g. ISC CHICAGO IL (USPS) for days or more than a week
3. inbound into customs
When a shipment is randomly held for customs inspection, there will be no further updates until it is released. Please note that we cannot expedite this process. If you require timely delivery, we recommend choosing FedEx shipping.
Thanks,
Daniel

Thanks to Billy for this nice picture of his collections of Jeff Hanko's excellent flashlights.
Billy bought these tritium vials while they were still available and had them shipped to Jeff's shop for vial installation. I must say that I am very envious of Billy having these gorgeous flashlights.

Please note: We take US$ via PayPal only. If we asked you to pay a certain amount of US$ to cover either vials or shipping fee difference of upgrading shipping method, please DO NOT change the currency at PayPal to our local currency, NT$. If you change the currency to NT$, we WILL ask you again for another 5% of that US$ amount. It is roughly the exchange rate loss at our side.
Important notice:
PayPal has changed their refund policy lately. We have experienced that PayPal did not refund the handling fee like they did before. So whenever you ask us to cancel the order, we will deduct 4.4% + $0.30 fee from your order's amount.
For example, you ordered $45 and chose $5 shipping. We as the seller are charged by PayPal total $2.50 ($2.2 for the merchant, shipping and $0.30 PayPal fixed handling fee). So if you asked us to cancel such an order, we will deduct $2.50 and refund you $47.50 only.

If you must add something to your previous order which we have not shipped out yet, please give us a note on your 2nd order especially when you are ordering twice with same items, quantities and colors. That gives us the impression of a possible error at your end by doing the ordering process twice as you thought your first attempt failed. We encountered this case before. So whatever identical order came in without any note will be treated as accidentally-released double order and be canceled and refunded from our side.
Thanks,
Daniel
