Pay just $5 for a $10 Starbucks eGift Card at Groupon. A code is digitally delivered that you can add to your Starbuck's card, if you already have one, and it's the best deal on a Starbucks gift card we are currently seeing. You can also send it as a gift to a friend. There is a limit of one per person and can be used in any participating Starbucks store within the U.S. The promotional value expires Sep 30, 2016, but amount paid does not. There is no sales tax on the card.
