Arenanet are making daily sales in the Black Lion store.
The most notable thing of it all is that they are bringing back some of the old stuff which was currently unavailable, for a short period of time.
Some of the discounted stuff is nice, whilst some is terrible offering no real value. Search the item up on the wiki before buying stuff, as some descriptions can be a bit misleading.
