I've been an Audible member for two years and i love it. I get one audiobook a month (at a much lower monthly cost than buying an audio book every month without being a member) and they often have sales where I will grab a few because they are very low-cost.
I've cut back a lot of things in my budget but my $14 a month to Audible is still there because I get 12-18 hours of entertainment out of that $14.
