Vroom与Thrifty租车疑问

昨天在Vroom租了辆 Toyota Corolla Ascent Hatch同时收到Vroom和Thrifty发来的两封确认邮件

1.Vorrm的确认邮件

Vehicle Rental: 139.08

Tax: 13.91

Vehicle Registration Recovery Fee: 24.20

ADMIN R/F: 6.20

PREM LOC: 30.12

Total Cost: AUD 213.51

2.Thriffty的确认邮件，邮件中关于charges如下

Estimated Mandatory Charges

Rental Time Charge $180.92

Administration Fee (3.5%) $7.10

Credit Card Surcharge (1.5%) $4.05

Goods and Svcs/ GST (10%) $24.96

LOCATION SURCHARGE (19.5%) $39.57

Registration Recovery Fee ($5.50 per day) $22.00

Total Estimated Mandatory Charges $278.60

Estimated Grand Total $278.60


请教各位大家从两封确认邮件的价格到底以哪个为准，我是看到thrifty要278.60才从vroom上订的，怎么htrifty发来的邮件还是278.60呢？麻烦有从voorm和thrifty租车经验的游四海旅游儿帮我解答下，感激不尽！
