拉扯长达五年的社区团购拉锯战，随着美团优选的彻底关停推出后，画上了句号。 对很多人来说，这完全就是现实版的欧亨利式结尾。 情理之中是因为今年 6 月份，除浙江、广州之外的美团优选站点就已经关停了。 而意料之外则是，很多人都以为剩下两个核心城市，起码能苟过 2025 年。 赢了，又是拼多多赢了。 现在，拼多多麾下的多多买菜成了目前全国性社区团购的第一、唯一赢家。 一位已经干了快 4 年的美团团长 ruby 和差评君说，他们完全没有想到。 因为美团一退，意味着之前砸掉的那几百亿，打下的江山、搭建的数万个仓储节点、培养的用户心智、一个个村子跑出来的团长，全部拱手送给拼多多。 多多买菜这边自然也没辜负美团的" 好意 "，连夜进场捡漏。 先是捡了用户。ruby 和我说，美团没了之后，她本来已经不打算干了。 但架不住小区居民都不同意，大家已经习惯了便宜菜送到家门口的感觉。最后没办法，在大家的要求下她开了多多买菜站点。 更夸张的是，很多地方的多多买菜直接爆仓了。。。逼得人家连夜发通告，把截单时间提前了整整 1 个小时。 有用户反映说，第二天的提货时间也从早上的十点，延后到了十一点左右。 甚至有网友说，都给多多买菜整涨价了。 ...
