I just got Mass Effect 3 Digital Deluxe on sale for $14.99 (50% off regular 29.99). I have the first two games already, so I'm happy with this.
They also have ME 2 Digital Deluxe for the same price ($14.99). And the Mass Effect Trilogy for the same. The Trilogy contains all 3 games, but only some of the extra content for ME 2 and ME 3. Just depends on what you want.
I'm not sure how long the sale will last. Couldn't find a date. There are other games on sale too. But I've been waiting to find a sale for ME 3 ever since getting the other two on sale and found this just now!
I've been replaying a bit of Dragon Age 1 and 2 lately, but I think next up for me soon will be Mass Effect!
