Long John Silvers has a printable coupon for a free medium Iceflow lemonade with any meal purchase at regular price. I don't go there very often since I'm not a fan of seafood. Ours is a combination LJS/A&W in Fredericksburg, so if I stop by, it's for the A&W out of the tap with a frosty mug!
Go to http://www.ljsilvers.com/coupons/ and if you are already a member, log in with your email. If you aren't, sign up and then you should be able to advance to the page where you can print. The coupon expires 9/30/2010. It's 103 degrees here with a very high heat index, so right now frozen lemonade sounds really good!
