Google Pay up to $9 cash back: $3 on your first 3 food or grocery payments using G Pay balance

Activate the offer in the Google Pay app.
You must be opted in to Google Pay Rewards and have a balance in your Google Pay balance card. This seems to mean you have to change to G Pay debit Visa as your default payment method before making the transaction and have enough balance on it to pay for the transaction.
If you have a different credit card set up as the default, open the G Pay app, click on the credit card you are using at the top of the app, then slide over to G Pay debit Visa (to the left of my Costco Visa in my app).
Minimum $5 spend per transaction.
Use your balance at qualifying US grocery stores and restaurants accepting Google Pay.
While supplies last.
