Early Wednesday morning, Groupon posted a Starbucks deal sure to excite fans of the Seattle-based coffee chain -- $5 for a $10 Starbucks gift card.

Rich Williams, senior vice president of global marketing for Groupon, told The Huffington Post that the deal marks a milestone for the company.

“We are celebrating our 5th birthday with our biggest ever deal for Starbucks, available exclusively on Groupon's new searchable website or mobile app," he said in an email.

Groupon ran the same Starbucks deal earlier this year, and it proved wildly successful -- hundreds of thousands of people bought it, and the deal was sold out in a matter of hours. "Our last deal helped us make March 22 (2013) one of our biggest days in Groupon's history," said Groupon representative Tim DeClaire.

At time of writing, more than 25,000 of the current Starbucks deals had been purchased. The deal is only available for a limited time (and there's no telling how long supplies will last), so don't dawdle if you're interested.

UPDATE 11:20 a.m.: More than 100,000 deals have now been sold. Yowsa!

  • Starbucks Iced Coffees

    In a quick taste test, The Huffington Post preferred the regular and low calorie versions of Coffee + Milk. We think, however, that the vanilla and caramel versions will appeal to those consumers who enjoy flavored coffee drinks. The drinks aren't as caloric as other Starbucks offerings; they pack between 50 and 120 calories per each 11 oz. bottle.

  • Starbucks Refresher In Valencia Orange

    We also tried the new flavor in the Starbucks Refresher caffeinated fruit juice line, Valencia Orange. It packs a sugary punch, which may appeal to those with a sweet tooth. We thought it tasted a bit like <a href="http://www.sunnyd.com/" target="_hplink">Sunny D</a>.

  • New Salads

    The Huffington Post enjoyed all three salad bowls (Hearty Veggie & Brown Rice, Chicken & Greens Caesar and Zesty Chicken & Black Bean), although none are particularly groundbreaking. For a quick meal on the goal that's not too unhealthy, though, these fit the bill.

  • New Sandwiches

    The sandwiches weren't available to sample, but we like the idea of deli sandwiches that are 500 calories or under.

  • Caramel Ribbon Crunch Frappuccino

    This decadent new Frappuccino wasn't available to sample either, but even the Starbucks rep admitted that this new drink is quite the "indulgence. We're incline to agree. The blended beverage made with caramel syrup, Frappuccino roast coffee, milk and ice before it gets a drizzle of Starbucks' new dark caramel sauce, a hearty topping of whipped cream, even <em>more</em> caramel and a caramel sugar topping.
