People tends to treat money differently based on where the money comes from. E.g. you tend not to attend a concert if the ticket was gifted by someone instead of going to concert if you paid $100 for it.
Same thing here with discount. If you keep thinking spending 10K will get you 1500 discount, you tend to overpay for items or buying unnecessary items to reach the 10K with the discount in mind.
This is why it's not useful to count discount as "return".
一个月不到额度够了，要不要继续撸几张？
如果是一定要花的钱，刷这个卡也是刷，刷别的卡也是刷，那干嘛不刷这个卡，刷够了钱数拿1500 bonus呢？
实际上在撸卡这个行业还有个术语叫manufactured spending，就是本来没有开销的需要但是硬要花够钱数，咋办呢？买Gift card，买money order，然后想办法把现金套出来，专门去赚bonus。
有钱人的生活是我这种穷鬼不能想象的哎。据说纽约去个米其林餐厅就能人均消费1千了。那是我这种穷鬼断不能舍得的
