FF XIII shipment is 1.8 mil - Confirmed

[Key2001]

I could be wrong(have no way to confirm it), he is stating that the 10% only applies to online orders.  Although this post would seem to suggest otherwise.

Even if the discount isn't due to the point system they have setup, it seems Sofmap has a history of offering 10% to 15% off new releases.

"Sofmap*, Sakura-ya, Bic Camera, and other big chains outside of Akihabara usually have better deals on brand new games on release day, offering 10% to 15% off retail."

"Sofmap (store in the backstreet, around the corner from the one on the street to Namba sta. this is *the* place for new releases (usualty 15% off all new releases, so its cheapest too) as well having a large amount of second hand games/anime/manga, its 6-7 floors)"
