Weekend Sale

Fyren - Heavens Tear

from the announcement page:
"You thought we would stop there? Also this weekend only we will be offering the ever popular Battle Pet Packs! These packs are for Venomancers looking to acquire the Hercules or Phoenix pets! Gather enough of these items and turn them in for your reward!"

The pet packs are already in cash shop, i assume it means a sale right?
