Major Nelson has posted the Xbox Live Marketplace schedule for the next few weeks, including some good deals and one strange one. This week's Deal of the Week is for Mass Effect 2 DLC. Gold members can snag "Lair of the Shadow Broker" and "Kasumi -- Stolen Memory" for $3.50 each, half the usual price. "Arrival" is also half-price at $5.

DLC for several Microsoft-published titles is also on sale, including content for Halo: Reach, Gears of War 2, Forza 3, Fable 3 and Alan Wake. This sale is not part of the Deal of the Week promotion, and appears to be open to both Gold and Silver members of Xbox Live.

As for next week's deal, well, it's a bit strange. Microsoft is offering the ability to change your Gamertag at a discount. It normally costs $10 to change an Xbox Live moniker, but next week's "deal" drops the price to just $7. So, if you hate your Gamertag but not quite enough to justify ten bucks, next week's deal is for you.
