Hmm...OK, if you really want lossless mp3s, I guess this is a good deal for you, but I'm not sure why else you'd use this service...
If you're a collector, you'd want the whole package, and in the case of digipaks, you can't even get liner notes through this service...
If you just want the music you can in most cases download the music...
So the audience is 1) people who want lossless mp3s and 2) people who want music that isn't available for download? which I assume is a small percentage of the music being offered for swap.
