I can't remember, and subetalodge doesn't say, but I believe the potion of purity was part of the spring stock in the MC, right?

It should be. If I remember correctly, the scribble pets were released during April fools day, so spring would be fitting. :D

It is a spring item. Here's a link for a list of the seasonal items. ">http://subeta.net/forums.php/read/6187/Deadlines-Retirement-Reminders-updated-1229/1/

Three months til? Hm. Well, I think I can do that! XD Thankyou! I thought it was spring stock, but it's been awhile, so I couldn't remember if it was spring or summer.
