英语和汉语在打折的说法上一般是相反的，在美国商场如果看到打折，只有数字，90%，那指的就是1折，90%和90% off（off就是指把90%扔掉嘛） 是一样的；而楼主的第一句at a 60% discount，比较书面化，符合中国人习惯，用得比较少，可以直译为6折
at a discount 打折扣；不受欢迎，没销路
special discount 特别折扣
discount price 折扣价格
quantity discount 数量折扣，大批量折扣
discount for cash [经]贴现
cash discount 现金折扣
discount factor 折现系数；贴现因素
现在都是流行用领券app了，而且会网购小伙伴，几乎人手一个或者人手几个，像我是下载了好几个，对比了好几个。因为是省钱目的，所以最后挑了折扣高的，返利高的。因为大家的券都是一样的，返利配比各不相同。我用的这款，淘宝，京东，拼多多都能领券，返利目前是最高的。好用，简单
