凑单

• Pinyin: còu dān
• Hanzi breakdown: 凑 (make up / gather) + 单 (order) -> add items to meet an order threshold.

Meaning

To add extra items to reach a discount threshold, free shipping, or coupon requirement. It is a common shopping tactic.

凑单 often appears during big sales when coupons require 满减 thresholds. It can save money, but it can also lead to unnecessary purchases.

Examples

1. 还差十块包邮，我随便凑单买纸巾。 I'm still ten yuan short of free shipping, so I'll just add some tissues to my basket.
2. 为了满减凑单，最后反而花更多。 I added extra items just to hit the discount threshold, and in the end I spent even more.
3. 凑单商品最好选日用品，别乱买。 For filler items, it's best to choose everyday essentials rather than random things.
