New Prices Permanent?

So DL has finally been updated, but I've been having trouble finding out if the new prices are permanent [which I really hope it's not], hence why I've come here to ask if anyone knows if it is. Also, let's say, if I buy one Glacial Sabres Item Pack for 250 Plat (or any of the other weapon packs), do I automatically
get the legendary Glacial Sabres on my first buy, or will I have to keep buying the item pack until I finally get it? Anyone who's recently bought any plat weapon packs, please tell me, I've been dying to know. :)

- Thank you in advance.
