"Like" Honest Tea on Facebook and allow the the Honest Cities application to send you an email and post on your wall and get a $1/1 Honest Tea printable coupon! Be sure to click the back button to print it twice.
Note: Honest Tea won't actually post on your wall unless you use the Honest Cities application.
If you don't have a printer or your local store doesn't accept internet printables, you can also request that your coupon be mailed to you, although you'll only receive one coupon with this option. Just click on the small blue Help link at the bottom of the "Your Coupons are Waiting" landing page to submit your mailing information.
