Google Pay 20% back at Burger King on $10+ purchase - works on gift cards! (confirmed by me)
Be sure to activate the BK offer on Google Pay, all accounts should have it. (not sure of expiration).
Went for Whopper Wednesday tonight and thought in addition to the food I’d get a gift card for $10. (that had to be rung up sep. from the food order). Sure enough I have $2 pending in my account. You can do a larger amount up to whatever the max cashback amount is listed on the offer. (ie. if $10 max, can get up to a $50 gift card)
