I have requested one of the Alibaba seller to send samples . Total cost of sample is only $1 but the supplier is saying fedex and dhl shipment charges around $32. I told the supplier to send through china post. Supplier says he never send before through china post. 1) Do you know how to send through china post? 2) I also bought couple of products from Aliexpress. The product cost is $0.75. They send through china post. The postage itself can cost more. Factor in envelop cost. I do not know how china post can send through such a low cost? The actual shipping fees are much higher in china post.
