在英国砍价时，你可以使用以下几种表达方式：
直接询问折扣
"Is there any discount available？"
"Can you give me a better price？"
表达不满
"That's a bit overpriced. Can you make it cheaper？"
"Hey, don't try to rip me off. I know what this is worth."
提出条件
"If you give me a discount, I might consider buying more."
"Can you give me a little deal on this？"
询问最低价
"What's the lowest you're willing to go？"
"Is that your best price？"
威胁离开
"If you don't give me a better price, I won't buy this."
"I can get this cheaper at other places."
记得在砍价时保持礼貌，并尽量在商家愿意接受的价格范围内进行。如果商家拒绝，可以礼貌地结束对话，或者考虑是否继续在该商家购物
