By registering at the local forum or social network, find like-minded people who want to buy the same thing (eg, food or children's toys). Typically, such purchases occur prepaid. Due to bulk orders, the price of goods is really low, and the experience will help organizers to procure safe. Over time, you yourself can learn to organize bulk purchases, and will receive a certain percentage of them.
