Quilt mags are just eye candy. Never have made a quilt from one, the instructions use methods I dont care for.
The only books I buy are by Eleanor Burns. She uses the best and easiest methods.
I have bought books thru Edward R. Hamilton because they are under $5 and shipping is 3.50 for the whole order. I highly recommend this book seller for all kinds of books.
I have a Kindle Fire but would not use it for quilting books or mags. It is great for free books but have not found any quilting ones as yet.
used to live by the Library and loved it. Great for checking out quilt books.
There are so many free patterns on line that buying them is a waste of money.
