"Buy some stuff, and we'll give you totally free stuff!"

For a limited time, when you spend $29 or more in the Official Guild Wars (online) Store, you will get a Guild Wars Bonus Mission Pack for free.

The Guild Wars Bonus Mission Pack will allow you to play through four pivotal moments in Guild Wars history. Earn unique rewards as you go face-to-face with Palawa Joko and his undead army as one of the key figures in the Battle of Jahai. Experience part of Cantha's turbulent past as you witness the violent Tengu Wars. Learn firsthand how the White Mantle rose to power in Kryta. And, finally, discover what became of Gwen after the Charr invaded her home and the Searing destroyed everything she'd ever known.

You can read more about the offer (and you should, because there's a catch or two) at the Guild Wars website.
