28 minimum as well? Can stock up groceries again

Yeh , no matter how many coins you have , max is 3000 perday.Means you have to find something to get exact RM100++  to use the coin and even then , if you have extra coin , you'll waste either free shipping again buying the next day.
Coins = points on Aoen day.
I don't see any significant different.
12% or just extra 2% coins compare points but expired 3 months
Points at aeonn is 1 year.even 10% you can use all up in 1 time buy.

How many coins did they give out ?

now different already , not everyone pump pcg  , and petrol price max float will stable at rm2.2 for 95 not like old days g0v simply petrol hike.
Anyway , no matter you buy the card or other stuff still you'll still need to spend extra $ and free shipping burn.Wonder those who get more than 10k coins need to buy separately everyday until finish up the coins before expired.

Now even you give out 100k coins expired in 3 months also headache , need to spend even there are thing not needed.As you said , pg card is the best but buying advance RM1000 petrol is a bit extreme.

Max 3000 coins , buy 2 separately = burn 2 free shipping.If buy 4 , free shipping for a month burn just like that.
If buy without free shipping also burn your 500 coins.

It's a merry go round.Over all , coins=points is good but What I dislike is expired in 3 months.At lease 6 months best 1 year.

I forget to add , those who buy stuff with voucher coins consider a voucher also.I still prefer direct discount 12% off voucher code compare to coins which force to buy stuff again.

The other day there's 40k+ coins /RM400+ for the winners

today's quiz 400+ ppl won with each getting 9.9k coins 

"15% Coins Cashback voucher - Min spend RM500, capped at 10000 coins on selected products"

Can I check if 100 coins = RM1? Will we get to know how many coins we can win at the point of transaction?

Why win?
You can see the coins you will get at the bottom after you select the voucher.

I see...the no. of coins that we can get is certain then. Thanks!

On coin utilisation, the max 3000 coins per day should apply then. If I purchase something at RM30 and utilise 3000 coins, I effectively don't need to pay any cash right?

No. If I am not wrong, max 25% of your next purchase on coins.
I am using the coins to buy PGC.

No. If I am not wrong, max 25% of your next purchase on coins.
I am using the coins to buy PGC.

so even if I buy a RM30 powerbank I still need to pay some cash ?
