I dunno, maybe, considering it just came out, that the deluxe edition was something like 80 USD retail, and that this includes 20-30 USD worth of DLC, yeah, I suppose you could call it a good deal. You may not want to pay that much, but it's quite a bit of recent content discounted fairly steeply (for recent content).
Sorry if I stepped into the "games are only worth $10 or less" part of the forum. Mass Effect 3 is worth $60 easily, and $48 with all the DLC included is certainly a nice price.
And just imagine, if they would have stripped even more content from the base game, then sold it separately as 0 day DLC for $100 or $150, and now would give you the whole thing just for $47.99, that would be the deal of the century. :P
And it really would, if the DE owners would get a proper ending(with Directors Cut DLC XD), sadly this is not the case. :(
