Free is everyone's favorite price. If you're wondering how you'll pass the time this fall and winter, Amazon has some free entertainment offers in store during October Prime Day including audiobooks, music streaming, and Kindle books. Here's how to score these free deals.

Bear, the maker of our favorite side sleeper mattress, is also running a sale during Prime Day. It's got 35 percent off sitewide with the code PRIME, plus two free pillows with any mattress purchase. It brings the mattress to the price we usually see it available for, though the $150 worth of pillows makes it a bit of a discount.

Amazon and Target have been holding savings events this week, but another major retailer, Walmart is also holding a sales event that will last longer than Prime Big Deal Days.
