Change it to after 28th will be a good idea... but your Due Date would be 18-20th of the next month.

u should get another card then to backup your wise card once you hit the limit

my top 3 active cc now = hlb wise + aeon watami + mbb2amex

Which part you need to explain ?

For me, I'll just cancel it and settle the outstanding amount.

Have to see your monthly total spending. If you can make it full rm2000, sure WISE and MBB dual cards. They offer the best rate with least T&C.
If above rm2000, UOB will be the next card.

MBB's master/Visa I can say is useless, I use it for installment plan only.
Yup, using CC to swipe cash using your way are good. I can say inside that rm1000 I spent on WISE, rm400 is I helping my relative to spend

When doing renovation, I use cash. As most of the time those ID or renovator that accepting CC charge higher than normal.
A rm1000 job they over charge you for rm3000, get back rm30 also can't offset another rm1970 lost
If you insist on what to get slaughter, OCBC's 1% unlimited will be good for you.

I see, then still OCBC for your case, unless you want to shop at SenQ(or other higher price shop) which should be accepting AMEX. Those smaller shops I think they don't accept AMEX.
You need to have strategies on getting max cash back from this. As most appliances sure cost > rm1000.

Statement amount are based on posting date, cash back are based on transaction month.
Better change the cutoff date to end of month, easier to keep track.
Because last time I confuse on this 2, I missed the maximum cash back.
My cutoff date are end of month. Just say, I did a rm 100 transaction on 24th last month, the merchant only post it on 31th(which over the cut off date) which I hit the rm1000 on this last transaction. It won't appear on current statement, instead it will shown on next month's. So for last month's statement, I pay lesser at rm800(rm1000-100cash back-missed transaction rm100) but next month's statement come, I'll pay more at rm1000(rm1000-100CB+missed transaction).

Should be able to do so, but your cash back may be affected. At least OCBC last time when i change the date I do lose out some.
But WISE's cash back are calculated base on transaction date, so should not affected.

rm50 can already, but not rm49.99
You have more to learn on using this card

always prepare to buy mentos.
if end with rm0 = add 4-5 mentos.
if end with rm1 = add 3-4 mentos.
if end with rm2 = add 2-3 mentos.
if end with rm3 = add 1-2 mentos.
if end with rm4 = add 1 mentos.
if end with rm5 = perfect.
if end with rm6 = nevermind or add 8-9 mentos.
if end with rm7 = nevermind or add 7-8 mentos.
if end with rm8 = nevermind or add 6-7 mentos.
if end with rm9 = nevermind or add 5-6 mentos.

   

RM50.01 is always my pump figure... Dunno why the meter can't stop at exactly 50 ! 

I don't see there's any problem with it, as long as you swipe 10X first and make it rm1000 sharp every month to enjoy maximum cash back
