买一送一，用英语怎么说

buy one get one free...绝对正宗..商场都是这么写的:)

买一送一的英文： buy one get one free 例句： "This is a good deal: Buy 1 , get 1 free."这可是个好买卖:买一送一 As a matter of fact, the salesmanship of "two for one" is a good way of advertising.买一送一，实际上是一种不错的广告。 2 lether shoes purchased for the price of one.买一送一(买两双皮鞋只须付一双价钱)

楼上基本都说得对，国外 商店大部分都有这个 buy one get one free买一送一 buy two get one free买二送一 buy three get one free买三送一 等等，以此类推。
