Can you get them anywhere other than user shops? (other than random events) Thanks ^^

You can buy them from the TS when they restock.

---Dei Thanks ^^

I think they also stock in the magic shop, or you could get super super lucky and win one in the potion lottery.

thanks ^^ I don't know if that would ever happen to me XD

I think you can also vend them from the Burning Change Vending Machine. I've heard of someone getting one there.
