Since switching over from DBS Multiplier to POSB Cashback Bonus on 8 Aug 2020, I had received the POSB Cashback Bonus amount in Aug & Sep. I blogged why I made the switch here (Link).
My cashback amount would have been around 14x lower if I were to remain in DBS Multiplier.
You can calculate your potential cashback amount via DBS Multiplier & POSB Cashback Bonus calculator in their website to see which program will give you higher amount.
