Getting Cheap EBooks (or How to Clog Your Kindle on a Tight Budget). A great way to fill up your Ereader. This is an excellent blog! I use all the sites to get books including subscribing to Kindle Unlimited which you can borrow up to ten books at a times and you can do that twenty times a day or more if you wish! It’s a great way to get a lot of reading done… You don’t keep the books but you get to read lots! I will tell you that you fill up your kindle or Ereader super fast with all theses sites but it’s well worth using them!
