A repeat of their 11/11 promo, Grab is giving 4,000 bonus Grab points (worth at least S$8) when you make a transaction with GrabPay, GrabPay Card, or PayLater on 26th November 2021:

Activity Reward
Spend with GrabPay, GrabPayCard, or PayLater with min. spend of $80 9% (45 points per dollar, capped at 4,000 points)
Spend with GrabPay Wallet (GrabPay Card included) Up to 1.2% (6 points per dollar for Platinum members)
Spend on groceries, fitness memberships, streaming services, software, app, e-book purchases, dining/takeaway meals, and telcos 0.8% (4 points per dollar, capped at 500 points per transaction)

Combined, they represent 11% rebate in the form of Grab points, though this rate is good for only $80 to $88.89 of spend. Regardless, it’s an easy way to get a bunch of Grab points which become even more valuable during redemption sales. These boosters and flash sales happen frequently enough that the rewards can add up to a tidy bit each month.
