For XBox users who are interested in getting Mass Effect 3: Citadel (1200 MSP = $15) at a slight discount, Newegg is selling 1200 MSP digital codes (i.e. instant delivery) for 15% off with promo code 15OFFXBOXLIVE. This takes the net cost of Citadel down to $12.75 and you don't have to contend with leftover MSP currency, nice and neat.
Mass Effect 2 (Playstation 3) is also being featured as a weekly gaming deal for 40% off ($12). The PS3 version of Mass Effect 2 uniquely includes most of Mass Effect 2's premium DLC (except for Arrival).
On the branded peripheral front, Newegg is offering the premium Razer SWTOR gaming headset for 46% off ($70). It's their first week of Razer sales, so it's possible that we'll be seeing some Dragon Age and Mass Effect branded products in subsequent weeks.
