以优惠的价格用英语怎么说

嘿，记得上次我朋友去超市抢购打折商品吗？他用了那句“Buy one get one free”简直抢到手软。所以，用英语表达“以优惠的价格”可以说成“at a discounted price”或者“on sale”。等等，我还想起个事，那天他竟然还用“half off”买到一箱巧克力，划算得我牙痒痒。

Hey, when you wanna talk about getting something at a discounted price in English, you can say, "I got it at a great deal" or "I scored it at a super-low price." It's casual and friendly!
