If you have yet to pre-order Star Wars: The Old Republic prior to its December 20th launch here in the U.S., Amazon has a new pre-order bonus that may be worth your while...
"Pre-Order Star Wars: The Old Republic and get early game access and a color stone to change your weapon effect. A one-time use code for early game access and color stone will be sent to you via email after you have completed your purchase. Limit one code per customer. Codes tied to canceled orders will be deactivated. Amazon reserves the right to change or terminate this promotion at any time. Offer valid when shipped and sold by Amazon.com, while supplies last."
The pre-order bonus looks to be available for both the standard and collector's editions.
