two for one
或者
buy one get one free
简称(BOGOF)
下面是我查找词典的句子，比较权威：
《剑桥》You're onto a good thing with this buy-one-get-one-free offer at the shop. ♀ 你碰上好事了，商店里有买一送一的活动。
《朗文》Take advantage of special offers and BOGOFs in supermarkets. ※ 要利用超级市场特价和买一送一的机会去购物。
买一送一：
Buy one and give one
Buy one get one
buy one get one free
