Hi there, I just reading first post and i found out that fuel rebate is intresting, this lead me to citibank site, and i found out that, why there is so many type of CC? in my mind is just silver gold and platinum, and now i see, citibank shell card, airasia card, giant card.. if I always deal with these 3 (airasia, giant and shell), meaning that i should get all in order to get the discount?
