Not reliable. Running snail cross-border e-business school is not reliable. I started to do foreign trade in 2009, and I came into contact with Amazon on 20 14, stumbling for so long. I know this smell best. Amazon is a refined operation, and its hard costs include: procurement costs, office space, warehousing, accessories, workers' wages, and logistics costs (much more expensive than domestic logistics costs, goods flow to the United States, and the current unit price is 6544 in June 10). If you send a red bill such as UPS, the price is 45 yuan), Amazon commission (basic 15 points), exchange loss (basic 1 minute) and evaluation, Amazon activity fee (spike 150 US dollars), European value-added tax (German 19%, UK 65430).
