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.
"can't help but" is normally interpreted as： 禁不住就，忍不住就；
"They discount so much I can't help but buy!"
A direct translation is: 他们打了好多折扣，我忍不住就买了/我没忍住就买了. More Chinese way: 他们的折扣力度太大了， 我没忍住就买了。
Unlike: 不像； 和... 不一样；和... 不同;
"Unlike the Chinese, the British add sugar to their tea."
One possible translation is: 和中国人不同, 英国人往茶里放糖. More Chinese way can be: 英国人和中国人不一样， 他们（习惯于）往茶里面放糖.
"They discount so much I can't help but buy!"
Direct translation : “他们打了那么多折，我不买不行呀！”
But for the part "I can't help but buy!" can translate into many option, i just pick out one that i think is the suitable ones.
small info : the discount compare to china is a different phrase. If is 25% discount in mandarin we would say 七五折, which is 75% of the original price.
For Unlike, 不像 i think is acceptable.
这家店打折这么多，我忍不住就要买买买。
can't help 在词典里的翻译通常是“情不自禁”，不过这里如果用“情不自禁”显得有点书面语。通常聊天，直接用“忍不住”就行。
与中国人不同，英国人往茶里加糖。
