Recently I knew that sourcingmap.com (online store) is doing a discount activity by offering free shipping for all their products from 21th,Jan to 10th,Feb. Generous enough. I used to buy some items from Ebay and Amazon, the postage always cost me a little more or less. When I look the prices of the products, I was surprised. Some products were even cheaper than Ebay or Amazon’s. It was crazy, I know sourcingmap’s products are from China factory, the product will be cheap, while they charge free postage, how much will they earn? The profit margin is so less. I was wondering is this actually sourcingmap return to their customers? Anyone knew this? Pls leave me some information. If this is really true, I guess both internet user and its competitors will be crazy.
