You can get a free $10 credit at Buy With Me (a Daily Deal Site). This offer is through Discover so you must use this link to get the $10 credit.
Then, you can use your credit to purchase a $30 California Tea House certificate which is on sale today for $10 (found at Philadelphia). Shipping is free.
This will most likely go quickly. I just did this myself so as of my posting, this was available.
