Mr. Jones bought me a Nook e-reader for Valentine's Day. I never thought I would use an e-reader to read a book until I was chaperoning a concert at night and was cramming for book club. I loved it. It wasn't hard on the eyes like I thought it would be. You can buy books instantly. No driving to the book store. No killing trees. (I still prefer to buy cookbooks, reference books and children's books in paper). I can also buy magazines and newspapers on my Nook, and there is no magazine clutter in my house. You can lend and borrow books, but I hadn't yet found a friend to share with and my library's selection isn't so hot.
Then I read about this website in Real Simple Magazine ... it's called ebookfling.com:
You can either purchase book credits to use for book borrowing, or you get free credits when people borrow your books. I got 5 free credits right away. That's 5 books I get to borrow for free! Not bad. And now when I decide to purchase an e-book, in my mind I'm buying 3 books because I get my book and will eventually use it to borrow 2 books. Not all books for Kindle and Nook are available for lending, but I think the selection is pretty good.
If you try it, let me know what you think.
