I don't get any recommendations or unsolicited emails from eReaderIQ.
I go to the site every day and scroll through the list of new price drops in the two genres I'm interested in. Aside from that, I have a list of books that I'm monitoring for new price drops. Whenever I get an email notification from the site about a price drop on a book I'm monitoring, I do a little happy dance,
and then go off to buy the book.
I will happily pay a (small) subscription fee for this service. They've saved me lots of money over the years.
