I want to say a sentence such as:
They discount so much I can't help but buy!
I went as far as 这家商店打折那么多， but need help with finding a Chinese expression that has the same impression as "can't help but..." in English.
Also, how do you say unlike in Mandarin?
Unlike the Chinese, the British add sugar to their tea.
不像中国人， 英国人把糖放进茶里 （or 英国人在茶里加糖）
I came up with the above sentence and added some variety for the sake of it. Would also like some help on this.
