The Disney Parks Exclusive Droid Factory R3-H17 Astromech Droid is now in stock via the Shop Disney Parks Mobile App as of this post. Price is $12.99 plus shipping.

Just a note it is listed as "In Store Only", but the APP allows you to place a order (as I just did). Hopefully they will process these orders and not cancel them for the "In Store Only" technicality. If you need to install the Shop Disney Parks App here is the link to download.
