I think if you read at least two books a month, you've easily gotten your money's worth. Maybe even one a month if you're reading biographies or histories that normally sell for over $10 on Amazon.

As with Netflix, the real selling point is convenience. It's probably not a great deal compared to library access to a huge Overdrive collection, or using coupons to get cheap books from Kobo, but it's much simpler.
