这两天跟GNC客服联系了两次， 他们态度真不咋地。 表示只有产品过期才可以更换或者退款。即使产品保质期只剩短，不能在保质期内使用完，他们也不受理。GNC本身有30天money back guarantee, 从购买之日起30天内，不满意的话可以退还给GNC, GNC会扣掉运费，把余额退还。 但是对于我们海淘来说，很显然这条跟没有一样，从购买到运到坡上一般也要2-3个礼拜， 根本来不及退还， 更何况邮费很的能比东西还贵。　

所以还是一句话，团购有风险，参团需谨慎。 另外要对twin pack 这团受影响的团员说声抱歉，跟GNC追讨应该是实现不了了。我看了基本上best before 的时间 是5月， 大家这段时间尽快用掉吧。　

跟GNC 客服的email 截图还有他们的return policy贴出来。
