This is all over Twitter, but just in case you haven't seen it there (or aren't signed up for the Zuneta newsletters) there is a code for 20% off Rouge Bunny Rouge at Zuneta.com with the code ROUGEXMAS.
There is also code for free international shipping, which is FREESHIPXMAS. I think you can only use one code at once, so I'd go with the 20% off Rouge Bunny Rouge. If I could only have one eyeshadow (shivers a little at the thought) it'd be this one: Rouge Bunny Rouge Solstice Halcyon. I've actually hit the metal pan on mine.
