Due to difference circumstances in different countries at different time, we have to use our discretion in choosing our courier. All we need from our customers is the length of time in which they desire to receive their products, and we will choose the courier according to that requirement.

For example, sometimes you choose DHL as your shipping courier. But your place is rural place and need additional charges. In the mean time we found another shipping courier like Sino-Euro or Sino-US is similiar cost and similar deliver time. Then we would switch to it without notice.

Example 2. Our shipping agent do not ship to Russia via DHL. In the case Russia customer choose it, we would change to EMS which is the best shipping mehtod to the country. And in case the payment is not enough, our customer service people would ask for the extra payment.
