TERA, you might be happy to know that En Masse has just put the digital download copies up for sale.
You can grab the standard version of the game for $14.99, while the digital collector's edition will set you back a measly $19.99 (that's a whopping 60% off if you're counting at home). Both bundles include 30 days of free gameplay, while CE purchases also net you a Frostlion mount and a couple of stat-enhancing necklaces.
The sale runs through August 28th.
