No worries, no offense taken.
Everyone is free to have their own views.
We have our own reasons to shop there, and I understand that not everyone feels the same. And it does not even occur to me that Jusco is a "high class" place as you mentioned.
We just shop there because we can do everything in one location (like watch movies, visit bookstore, etc.) in one day, and we enjoy strolling around in the ambiance.
Giant and Tesco are grocery shopping places, which of course have very reasonable prices, but just does not serve our purpose.
We sometimes spend more than 6 - 8 hours in the mall, and I cannot imagine doing the same in a Tesco.
Not saying which is better, just that different people have different needs and preferences.

Well, as long as you're happy, more power to you.
I stay in Damansara, so I wouldn't know anything about Seremban.
On the contrary, both of us love 1U, as it serves our purpose.

Hey that's a good idea, get 2 cards and you get to select 4 categories.
I should consider that.

That's weird, never heard of such a thing.
Anyway, I only applied (and received) my WISE card, and I do not have the GSC card, so I do not think that they can say that these 2 cards are a "combo" or a "pair".
If you can apply for just one card, then logically you should be able to cancel just one card, individually.
The CS might be trying to pull a fast one on you, or maybe he isn't very clear about his product?

Really?
Well, that's the first time I'm hearing this, to be honest.
I didn't even know they had a combo.
I just went to the bank to apply for the Wise, and the officer also did not say anything at the time.

Ah OK, I think I misunderstood your original post.
I thought we can select different categories for the principal and supplementary cardholders.
Sorry...haha.
Wishful thinking.

Yes, that's exactly what I'm doing too...!
Set the payment to automatically pay on a weekend, to take advantage of the 5% cashback + 5x treatpoints.

Yes， I'm the principal cardholder.
Was thinking whether or not to get a supp card for the missus, but after doing my math, I determined that there was no further benefit of doing so.

True, that.
In fact, I've already maxed out my Watami card, and nearly maxed out the Wise.
The only card that I have not yet maxed out consistently is my MBB AMEX.

I see.
I wasn't offered the combo offer when I applied for the Wise.
Seems like a rotten deal, this combo thing.

True, but our monthly expenditure is already adequately covered, so having another Wise principal cardholder would no longer be of benefit.

Sorry to hear about your bad experiences.
For me, fortunately for all my transactions, the period between transaction and posting dates are usually 2 - 3 days only.
Touch wood.

Yes that's what I thought too.
But anyway, to be honest, these days, I have so many transactions on my cards that I easily satisfy the 10 transactions requirement, so I do not really count the transaction or posting days anymore.
I just check to ensure that the charged amounts are correct.

How do you ask the petrol station to clarify?
I'm not sure the workers there would even understand what are transaction and posting days.
Unless, maybe the station manager, I suppose.
