Liyan Chen, a grad student in New York, was chatting online recently with her cousin in China.
"He said, 'I want Abbott milk powder,' " Chen told me. " 'I want you to buy it and ship it back.' "
Her cousin wanted her to buy three boxes of Abbott baby formula, sold under the brand name Similac, and ship it to him in China. She did some research and found out the shipping alone could cost $80. "They're not from a very well-off family, and that really surprised me," she said — especially because they can buy Abbott baby formula in stores in China.
