只加油,assume costco gas price is 10 cents(91) lower than other gas station,
你一年开2万5千km,大车12升per100km,
共用3000升油,你每次都去costco加油,可以省300元。如果Costco比其他加油站少5分(87),你省150元。membership 110元,油费3600刀赚2.5%rebate (2%executive,.5%amex) = 90, 共省140刀到290刀。
2% 是executive membership (110 年费那种),而且只限于costco的消费
恩,看错了。不过Costco Amex卡加油有2% rebate吧。如果是executive会员,另加2%,是这样算的吗?你看掉了一个小数点,是.5%
