YMMV: (could be limited to new subscribers). Amazon is offering a 2 or 3-month subscription to its Kindle Unlimited service for $0.99 per month. If you don't cancel after the first 3 months, it's $11.99/month going forward. There's also a 30-day free trial offer option.

KU offers unlimited access to over a million eBooks and thousands of audiobooks, on any device.
