It will probably not be back in stock by the time the sale is through.
That's just the way it works around here sometimes. Usually if something goes on sale that I've had my eye on, I grab it fast because things tend to sell out during sale times.
There's a few items I'm waiting to come back into stock (like the Good Clean Love gift set) but it seems as though it's neverr back in stock (at least when I check).. I know that has nothing to do with your question, but like Elnoa said, the sale items go pretty quickly.
