I'm trying out for spending for multiple bill payment below 10 in multiple days too to see if it works.. haha! 

It will work as long as on different days.

I believe in order to receive CB for utilities category, you need to Standing Instruction transactions with thsee service provider.

If condition (2) supersedes, then you won't receive CB for:

1. payment via jompay in UOB website
2. payment made via TNB mobile apps

i just applied two uob card. salesman told me uob card first 2 years is free. and it can be waived by calling cs after that. is it true??

All cards come with first year AF waiver, anything promised by agent better get a black and white.

UOB ONE CARD need annual fee? No information stated at their website.

Yes, it has AF.

becoz cant find the AF from their website. Saw 70+ at RINGGITPLUS

Just save your UOB card details at the following online merchants/apps:

    Paypal
    Lazada
    Google
    Itunes
    Apple Store
    Uber
    Grab/Grab Taxi

for preferred platinum, i saw on uob website online stated the following merchants only:
so the rest like shopee, 11street dont have cash back?

You may try to top up Lazada wallet RM10 X 16 times on 1/5. Then you have Lazada RM160 credit kept for future use.

if i buy something on tesco online, the cashback is 2%(groceries) or 0.2%(rest)?

updated PDS, guess uob need to make it very clear between the distinction of "retail transaction" vs "swipe"

Any difference between  "retail transaction" vs "swipe"?

well, who knows what uob is thinking.

some ppl are still thinking a "swipe" is a physical action, whereas it can be considered for online/CNP transactions too. probably "retail transactions" covers both modes of card usage.
