Calculation steps
- 1Chinese "zhe" convention: X 折 = pay X/10 of original (8 折 = 80%)
- 2Final = 300 × 8/10 = 240.00
- 3Saved = 300 − 240.00 = 60.00
Common promo equivalences
| Promo | Equivalent | Condition |
|---|---|---|
| 2nd item 50% off | 7.5 zhe (25% off) | Two items of equal price |
| Buy 2 get 1 free | 6.67 zhe (33% off) | All three same price |
| Buy 3 get 1 free | 7.5 zhe (25% off) | All four same price |
| Spend 300 save 50 | 8.33 zhe (best) | Exact multiple of 300 |
| 8 zhe × 9 zhe stacked | 7.2 zhe (28% off) | Both apply sequentially |
| 50% off then extra 20% | 4 zhe (60% off) | Stackable |
Beware the "inflated original price" trick: some merchants raise the base price before discounting. The equivalent discount only matters against the item's historical selling price, not the tag price. Also note Chinese "zhe" is the inverse of Western "X% off": 7 zhe = 30% off = pay 70%.
