Picked up the
Mass Effect Trilogy, too.
The price ($13.99 for the moment) was very good considering that you've got to buy the discs new (About $30 here in USA) in order to be sure about the codes.
Was I able to completely sort out whether I will be able to get every single piece of DLC listed in this
IGN wiki? Not totally, but it seems pretty sure that I'm okay.
Here's what shows up on my Download List after purchase
-Mass Effect 7.0 GB
-Mass Effect 2 11.9 GB
-Mass Effect 2 Cerberus Pack 695 MB*
-Mass Effect 3 13.8 GB
* Connect now to receive: Zaeed, a lethal gun for hire who will join your squad, bonus armor and weapons, a series of vehicle missions, the Dark Horse interactive Mass Effect™ comic "Genesis" and more. Note: Full game also includes all of the contents of the Cerberus Pack.
And here's what additionally shows as free DLC on PSN
