I see another benefit of using Amaze card... by default, my Amaze card is linked to my MB F&F.
When using my MB F&F directly, the posting date is normally 3-5 days after my transaction date.
However, when I used my Amaze card instead, the the posting date is reduced to 1-2 days after my transaction date.
This is particularly useful during end of the month when I realized that I have some shortfalls to meet for the minimum spend in order to get the favorable discount rebates.
Anyone have made similar observation?
