If you enjoy reading basically anything at all then an E-reader is for you. Nowadays e-readers have developed into outstanding pieces of equipment and are only getting better. There are many different companies producing their own e-readers and competition is fierce, thus bringing more savings and quality to you.
I personally use the Amazon Kindle but there are others just as great. I can find many free e-books to download and if they are not free they are usually cheaper than the hard copy.
If you don't want to purchase an e-reader right away then amazon and Barnes and Nobel both offer free apps that allow you to read your e-books on your computer, phone, or tablet.
The apps sync with each other so you can pick up right where you left off.
Here are some places you can find free e-books:
Assume you read two books a month at a $15 each over a year, you will have spent $360. Reading free E-books, you will save $360 a year. PT total savings = $360.
