A rewards programme is typically intended to encourage spending, but being limited to what available on the Play Store may appears to be a rather bleak prospect. Google considered this, and we learned last year of plans to allow Points redemption against hardware purchases from the Google Store.
Discounts through “partner offers” from DoorDash, Instacart, and Povo were among the new redemption options advertised in the tweet. You could, for example, save $5 on your next Instacart grocery order of $35 or more, while DoorDash offered a $10 discount. You could also trade 2,500 Play Points for $25 in Play Credit in exchange for a cool branded t-shirt from the Google Merchandise Store.
