Just received this in the mailer today….
It’s certainly hard to believe that time has passed us by so quickly–but yes, Grab is turning four this month.
To enjoy the promotion, simply use the code GRAB4YEARS to get up to $15 off. This promo is valid every Monday in June (i.e. 6, 13, 20, and 27) and is valid only on GrabCar rides via card payment. You can only claim the code once every Monday and the catch is that there are only limited redemptions available per day.
To find out if you qualify, simply enter the coupon code when booking; if it allows you to redeem it, you’re good to go. T&Cs here.
