If so, you could earn a $5 Starbucks gift card with the purchase of the three qualifying Starbucks and/or Tazo products from your grocery store in a single transaction. The promo is valid through Tuesday, December 31. To get your $5 Starbucks card, save your original grocery register receipt and UPC codes from purchased products.

Don’t forget the cream and sugar.
