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%.
