In order to better understand the price relationship, we introduced the concept of "Official Rate":
1.
When the group rate is 1: If the official price is 1 dollar, will deduct 1
2.
When the group rate is 1.65: If the official price is 1 dollar, will deduct 1.65
In this way, we provide users with a more flexible and transparent pricing mechanism, allowing them to make the best choice based on their needs and budget.
