To answer your question....
I clicked on your link and this was up on the site:
"Received this from Starbucks corp so we're taking this coupon down. Please check out http://www.freestuffcrazy.com
for more free stuff!
I wanted to let you know that there is a counterfeit reproduction of a coupon offering a free Tall (12 oz) Starbucks iced beverage posted on your site. Someone has altered the original coupon by reproducing it online and removing some of the legal language. This offer and other Starbucks promotional offers are only valid in their original format. Please remove this from your site. Thank you!"
They had already removed the coupon.
Too bad, it would have been nice to get that coffee and give it to a friend.
