Through July 19, those with a Facebook account can sign up to share a coupon for a free pint of Starbucks icecream with a friend (you can send it to yourself, too, if you'd like!). Starbucks has promised to give away up to 20,000 coupons per day (a maximum of 800 per hour), so everyone should be able to get in on this great deal!
Go here to request your free coupon. I just did this and it was running a little slow for me. I had to refresh the page and then it worked.
Thanks, Saving Dollars and Sense!
