I use Pixel of Ink too. All the free Kindle books are listed there several times a day. Usuallly most are free just for a few hours but there are many available everyday for free. I seldom buy books for my Kindle. You probably got a free month of Amazon Prime when you bought the Kindle and you can borrow books from Amazon Lending Library using your Prime account. You have to register your Kindle using any credit/gift card that has an exp. date to be able to download books and apps for free.
