Their online shop has been offering 20% off dolls from 2007 and earlier. I gave in and grabbed three older friends, and a new-ish Tamaki I've had my eye on for a long time.
The older three characters seem to have fallen out of favor. I prefer the older looking designs to Angel's Garden, Ayano, Mirai, Puffy, etc... I'm especially happy with Abel, I love short haired dolls.
Now, to wait on the shopping service.
