对于国内的跨境电商来说，近几年中东大促的效用对大多数人是递减的。一方面用户对每次的大促的大同小异难免有些疲劳，另一方面竞争也是越来越激烈- 一直到去年底还是有新卖家相信卖账号的代理，当了新韭菜。

而且虽然不管是传统巨头还是新兴物流公司，大量的投入之后到了旺季运力还是不足。当然，不可能用旺季的需求去规划全年的物流基础设施投入-“亏死”（业内人士应该知道前车之鉴不少）。如果不能有效征集、利用到社会化运力的话，估计对中小电商来说旺季永远是可望不可及。虽然社会化运力这个事在失业率居高不下的沙特看起来是合情合理，但是真正做起来永远就是另外一回事了。

2018年黑五之后，墨腾就抛出了这样一个问题，中东对于中国跨境电商来说，是否饱和？
