EA has finally offered the complete DLC bundles for Mass Effect 2 and 3 for sale on Origin. So now you can grab the Trilogy Pack and the ME2 + ME3 DLC bundles to complete the entire trilogy.
In the past, you used to have to buy "BioWare Points" to pay for the ME2 and ME3 DLC individually. EA or BioWare had never released a "Game of the Year" or Complete edition for ME2 or ME3 that included all their DLC. Even the "Trilogy Pack" was incomplete and missing many ME2 DLC and all ME3 DLC. Those stupid BioWare Points never got a discount or went on sale, so in the past you would have to spend over $100 to buy BioWare Points to pay for all the DLC for ME2 and ME3 in order to experience the ME trilogy to the fullest.
About two or three weeks ago, EA finally bundled all the DLC into two packages less than a month ago, but only sells them on Origin. Right now, the DLC bundles are $25 each. Origin's best discount is 75% off.

BTW, Dragon Age 2 DLC also got the same treatment.
