I'm on a limited enough budget and I have a narrow enough genre of interest, that so far that hasn't been a problem for me. I won't download something just because it's a freebie, I have to think I might actually read it
. Even with that, though - I have huge "to buy" lists at Amazon, BN, and Books on Board. And I've started a list of new releases in the genres I'm interested in, so I can keep up with what's coming out when. I can tell you that the list is already a lot longer than the available money I'll have.
