Someone else pointed this hack, so I don't take credit:
If you have any jules, you can pick an item from the jule box section:
http://www.julep.com/shop/jule-box.html
Add warm wishes to your cart:
http://www.julep.com/shop/12-days-2014-day-9/warm-wishes-trio.html
Use KARMA
Check out, and everything is free.
Devon is only 400 jules right now -- so it's like the equivalent of getting a whole box and addon for just 400 Jules.
eta since I put this in the enablers section, if you don't have any jules, here are a few really good deal items.
These are all $10 for two polishes (so $10 for all five polishes with Karma):

http://www.julep.com/shop/12-days-2014-day-9/sugar-plum-duo.html
Or, add something to your cart (literally anything)
Click checkout, it will give you the option to select addons:
(the little lights are super tiny, but it might be a good deal for some)
Click check out, go back to the front page and click on your cart, and remove everything other than the three wishes trio and your addon, then check out.
These are the cheapie addons:
