But credit card can earn points, get rebate, and get discount in
some places.
Yeah, earn 1000000 points to offset 10 dollars off your next
bill, whereby every 10 bucks spent, you get 100 points.
Another example, every quarter, for every example value of 300
dollars spent consecutively for 3 months, you will get a rebate of
10% that value.
So I pay up bills of 800 dollars every month
from say january to march, and they will give me rebate of 80 bucks
on my april bill.
As for discounts, 1 gets to eat free for every 4 paying adults
with, valid for this month only.
