maybe taobao not considered as groceries.
but i will wait the hard copy bill and have a look the categories.

You don't count that way... each category you add the total x 10% and round-up to nearest RM1.

Mobile transaction : RM29.90 --> Rebate : RM3.00
Petrol transaction : RM208.73 --> Rebate : RM21.00
Grocery transaction : RM393.82 ---> Rebate : RM39.00

The highlighted transactions = to those labelled on your Paper Statement ?

RM393.82 x 10% = RM39.38
Rounding to nearest RM1 = RM39

If rebate is RM39.50, then you get RM40 

It wont happen lah, how can spend just $5?

isn't it min need to spend 50 to get the rebate

U tried it before?
usually i just round up myself to get the categories to reach max but above 50

Tesdte means "confirmed" ? Which location?

I did a check on my historical records. I believe the CB is round up at category level and not per transaction basis.
Based on the above examples:
Category 1 : total spend = RM550, CB = RM55
Category 2 : total spend = RM200, CB = RM20

Based on my observation, the highest effective CB is 10.15%, where spend RM985 to get max CB of RM100.
e.g. Category 1 : total spend = RM325, CB = RM33
      Category 2 : total spend = RM325, CB = RM33
      Category 3 : total spend = RM335, CB = RM34
=> Total spend = RM985, CB = RM100, effective 10.15%.
I tried that in Jan (just for fun lah), spent RM985.10 and max out CB at RM100. 

Could it be your Taobao purchase is in RMB and after conversion should be around RM80 instead of ~RM149???

Hi all,
Reporting my first cash back...max RM100 with mobile paying through UOB payonline.

if my TNB bill exceed rm500 per month, can i swipe rm50 x 10 at the tnb autopay machine to entitle for the rebate?

Mean it fulfill the requirement to get rebate simply by split it rm50 x 10 times? Does it mean any transaction will do as long you have RM50 x 10 times charged regarding it's pay to same merchant or not?

How you sell back?

Crazy calculations all around. Honestly speaking, I really wonder why have to purposely go and buy things that you don't need for the 10% CB. No need factor in petrol and time?

Theres no need to be obsess with the numbers game. Just take it as someone gave you extra RM1150 to buy more groceries each year.

Unless you actually spent 3-4k each month on credit card, otherwise just a waste of time getting few cards to maximize the CB because after deduct GST, not much gain.
