If I’m online when Pam posts them (and if they don’t sell in the first 10 seconds), I post the new special items on the Facebook page. That’s currently the only place we’re announcing them.
We are not sending “new item” notices out for the special items because there is just one of them. We also don’t send out “new item” notices for the small one-offs that have been going into the store lately (random CP things mostly). I also put the one-offs on Facebook.
No idea on the other questions! 🙂
