Cool. With that I'm lacking only Batman: Year One and The Dark Knight Returns on my list of the must have Batman stories.
And yes, I could buy Year One now in singles, but when it comes to old, finished series I prefer digital trades. Why they don't always put trades on sale when they give a discount for single issues of the series is a question to me. It does happen, but rarely. In past few moths DC only did it with Fables, but that was a general sale of everything connected to this series.
Yeah, I wish DC put the digital trades on sale more too. I'm not a fan of buying all the single issues any longer, and prefer just to buy the trades. I ended up picking up Batman Eternal Volumes 1 and 2, Gotham Academy Vol 1, Batgirl of Burnside, and Grayson Vol 1, so all the New 52 stuff I hadn't gotten yet.
