Groupon offers a $10 Starbucks eGift Card for $5. (Search for "Starbucks" via the search bar at the top of the page to find the deal; it's the top result from the search.) It's among the best deals we've seen for a Starbucks gift card. (For further comparison, we saw a free $5 gift card with a purchase of a $5 gift card for delivery via Twitter last week.) Gift card expires May 1, 2014. Deal ends November 9.
