Amazon - Guild Wars Factions Pre-sale Disk for $1 Shipped!
 

Supposedly you need to pre-order the expansion game to get this pre-sale disc, but I was able to get to the final checkout screen with no problems. Not only that, but it also gave me free shipping. This is not the full game, but a pre-sale disc that gets you:

• A key that provides access to the Factions Preview Event on March 24th
  
• Access to Guild Wars Factions twenty-four hours before the official release date
  
• One unique item for each of the two new professions
  
• A "friend" key that gives one of your friends access to the Factions Preview Event on March 24th
  
• A 14-day, 10-hour trial of Guild Wars (original Prophecies campaign)
  
• A tactical guide
  
• A quick-reference card
  
• A CD that includes concept art, wallpapers, and in-game trailers

Again, I was able to get free shipping and actually arrive to the final checkout stage for $1 shipped without ordering the actual game. Hopefully it will work for you too. Well worth the buck. GUILD WARS FACTIONS PRE-SALE DISK SALE
