How is the carrying fee (upstairs delivery fee) calculated?

The carrying fee is calculated based on the floor and the order amount, with straightforward rules: ① Orders of 10,000 yuan or more (including 10,000) incur no carrying fee; ② For orders under 10,000 yuan, floors 1–2 are free; ③ Floor 3 adds 15 yuan per package, floor 4 adds 25 yuan per package, floor 5 adds 35 yuan per package, and floor 6 and above adds 40 yuan per package. Additional note: Items whose packaging can fit in the elevator incur no carrying fee. This item is listed separately in the quotation and will not be added on the spot at delivery.
