Was doing a study of Alliance Bank's credit cards and their cashback rates
http://www.alliancebank.com.my/ccard_cashback.htmlfound an interesting fact. since it is tiered, the effective interest rates are different and depending on your monthly usage patterns, the classic card may give more rebates than the platinum card
In a nutshell
Monthly usage Best rebates
RM0 - RM400 - Platinum
RM500 - RM1000 - Classic
RM1100 - RM3200 - Gold
RM3300 - RM5000 - Platinum
Interesting point to note that even with the cap at RM3000, the gold card still gives better rebates at RM3200 monthly spending compared to the platinum card.

If anyone wants the spreadsheet can pm me.
*Assumption: You:nique = Platinum card cash back tiers
The rebate is not bad cause with the gold PB card i have, to reach the same amount of rebate for RM3k on a Alliance gold card, I need to have spent RM7846 on the PB Card. Talk abt poor return.... Pb's only positive point is no cap on spending though at those high numbers.. you won't care abt a 0.X% of rebate anyway.
