Delivery Time

The total delivery time is the sum of the lead time and the shipping time.
Lead time = the period between your order and shipment of the ordered products. (It usually lasts for 1-5 days, shown on the product description page after the product name.);
Shipping time = the period between shipment and delivery of your order. (It usually requires about 15-20 business days dependant on the shipping method.).

But please note that any delivery time or date, time or periods mentioned herein, or otherwise quoted or communicated to you in any form or manner, are merely estimates and are not guaranteed, and may be subject to delays for a variety of reasons, some of which may be out of our control. For example, in some cases, your customs authority may hold your products which may result in a delay of the delivery. Except as provided in the next paragraph, we shall not be responsible or liable for any late delivery or non-delivery caused by such objective factors (for whatever cause or reason, and whether or not within our control).

If any product fails to arrive at you within 60 business days from the date on which your order or transaction was accepted and your payment was received, or from the applicable estimated or quoted delivery date, whichever is the later, then you may reject, cancel or terminate your order or transaction, in which event we will be solely and exclusively liable, and in respect of the late delivery or non-delivery and the resulted rejection, cancellation or termination of the order, you are entitled to the sole and exclusive remedy in the form of refund (interest-free) to the extent of any payment you have already made for such order or transaction.
