I just got an email from MySpiceSage.com about this offer. Unfortunately it expires Wednesday 2/24 at 1 pm EST, so jump in if you're interested.
For anyone who missed the sponsored deal on New Year's Eve (which was 8 Madagascar vanilla beans for 5.95, which was an outstanding price itself - here's the thread: http://deals.woot.com/deals/details/a033038d-238c-4960-ae3c-fb08d1616e05/8-madagascar-vanilla-beans#25), now you can get 10 Madagascar vanilla beans FREE with every order.
Yes, this requires you to buy something else, but their prices (and quality) are quite good and Madagascar vanilla beans are generally pretty expensive.
I've personally ordered from this company twice now and have been very happy with everything I've gotten from them.
