Came across this Facebook ad with promo code GROPM.
Applied the promo code to my account and it worked so it shouldn't be targeted like the other $15 off $20 Grocery Order deal on Ozbargain at the moment.
Terms and Conditions:
This offer is for 1 x $15 off total order value when you spend $20 or more from select Grocery stores via the Uber Eats app (fees apply). Maximum of $15 off order value applies. $15 off does not apply to fees. Delivery Fee applies. Service Fee applies to orders delivered by Uber Eats and is based on order value (before promotion or discount). Other fees may apply. Any remaining value is forfeited if order value is below $20. Valid for use on one order only. Promo code must be entered into the Uber Eats app prior to ordering. Delivery orders only. Offer cannot be used in conjunction with any other Uber Eats promos.
