From threeA Wiki
Bambaland is the name of the name of the official online store of threeA. Several online and brick-and-mortar retailers also carry threeA products, and ThreeA often has releases that are Bambaland exclusives or retail exclusives. Bambaland is usually in stock once a month with that month's significant ThreeA release, which is often announced with an update to the ThreeA Countdown Widget, however ThreeA has also recently begun ThreeA Resident Sales at Bambaland as well. Most monthly drop information is also announced on the ThreeA Production Blog and 3A Forums.
For Chinese speaking fans, a new alternative to Bambaland has opened called Bambasia.
