Oops! Someone at the Xbox Live Marketplace typed '800' instead of '0' when posting the new Rainbow Six Vegas Map Pack:

Tom Clancy's Rainbow Six Vegas Black Pack Downloadable Content for Xbox 360 Live was originally intended to be free content for the fans of Rainbow Six Vegas. We apologize for the error. All players who purchased the Black Pack will be reimbursed automatically within 8 to 10 weeks. The Black Pack will be posted Saturday June 30 and will be free of charge. Also, as a token of our appreciation for the Rainbow Six community, we are making the Red Pack free as of Friday July 6th as well. Thanks for playing and we hope you enjoy this free content.

Giving out refunds is the least they could do -- making the next map pack free as well is just classy. Thanks, Ubisoft!
