Newegg's Daily Deal section has the retail copy of Star Wars: The Old Republic on sale for only $9.99 with free 2-day shipping.
All retail copies include a physical copy of the game, an account registration code, and 30 days of free play time.
Although a free to play option will be available sometime this fall, I believe every account will need a retail registration code, with the MSRP rumored at $14.99. As an additional bonus, the new free-to-play currency will be given to all existing players for each month that they have previously paid, which will give you 200 "cartel coins" to spend when the game goes free to play.
