Awh, lemme see what I can find for free on kindle unlimited. Also, for the book lovers. Thriftbooks.com is where I get all my books as well, because at $10 they give you free shipping, and it's actually only 2-4 business days EVER. I love it a lot. The longest I've ever had to wait for books was over a weekend when I ordered, and I got 15 books for $40 at one point, and they have textbooks. Plus I get free 15% off coupons I can send to people whenever I want since I bought from them. They're used books, but they're excellent quality most of the time. I love them sooo much.
