yes, retail include offline and online purchases

for acquisition campaign such as “Apply Now for PB Card & Take Your Choice Home Campaign”, pbb quite strict to treat lazada as DM. others have experienced issue not getting the sign-up reward. not sure if they successfully gotten it after disputing with pbb.

to be safe and have peace of mind, avoid lazada if you're targeting acquisition campaign.
for monthly cb or cb-related promos, so far, lazada is "eligible" although identified as direct marketing (DM). i guess pbb whitelisted lazada.
read post #3 or PBB website.

i dont see how both cards can be the same   

Quantum MasterCard
5% Cash Back on Online & Dining transactions, capped at RM30 per monthly statement cycle equivalent to RM600 spend.

Quantum Visa
5% Cash Back on Entertainment & Departmental Stores transactions, capped at RM30 per monthly statement cycle equivalent to RM600 spend.
both cards are different. if u want online, then Mastercard Quantum is for u.
for pbb case, add supplemental + split statement = separate cb for each card.

usually for other banks/cards, supplement+principal combined cb.
yes

i'm aware of that. i already posted the xiaomi speaker on Jun 19 2018 here.

Not for today. Too late, first come first served.

You will never know until you try it.

It's 50:50

You DO or do not DO

mondays safest. tuesday also good.

wednesdays/thursdays risky but should be fine for now (early of the promo). when nearing end promo period, thursdays usually finish quota liao.

Boost top up is under Direct Marketing, so not eligible.
When did you perform 3rd top up on Laz wallet?

No. Boost is automatic Direct debit, not online transaction. You didn't receive OTP! So no rebate for Quantum MC.

adoi wait for it la

today only for week3!

Boost is really good, 50% rebate at some outlets! No need to cancel.
You can always top up BigPay first, then use BigPay to top up Boost!

The fund at your Boost account can be transferred to your saving account, you only lose RM2 for the transfer.

Using Boost on 11street can get shake back reward also :\

Can see from your posts that u learned the hard way cos u didn't do your homework. When did u first top-up Lazada wallet this morning? If done b4 8am, they could be taken as yesterday transactions cos it uses foreign payment gateway so have to do extra work to get them counted.
