Was just surfing Amazon and as of this post, they are taking preorders for The Black Series 6-Inch Jaina Solo. This is sold and shipped by Amazon with a price of $19.99 each with a limit of 2 per account. The expected arrival date is January 16th. Get them while you can, I am sure they wont last long!
If you dont see Amazon's listing, be sure to look at the "Used & new from" option on the product page as thats where I found it listed as backorderd from Amazon.
