EDIT: Judging by the traffic on this post, tons of Hiffers are taking advantage of this offer, so I wanted to bump it for anybody who missed it the first time around!
Good thing I didn't drift off to sleep quickly tonight, as it allowed me to clean my fridge and find this Groupon offer for a $15 Starbucks gift card for only $10. Seeing as how this is from Groupon, it's bound to die fast, so good luck. On a similar note, last week's free Starbucks k-cups offer that kept bugging out should be working again if you missed yout.
So if you're a fellow insomniac / caffeine hound (annnnnnnnnd I think I've found my problem), pick up a $15 Starbucks gift card for $10 before the deal expires!
