If you've ever looked at both AliExpress and Samsung's accessories store, you'd know that car mounts can range from the super cheap to the super expensive and there are dozens of different designs and concepts used to keep the phone stable despite the vibrations and accelerations of the car. One of my favorite types of car mounts are magnetic: they're usually sturdy, very simple to use, have less moving parts, and are super quick for placing and removing the phone.
If you love these types of mounts or you want to try one out and see if it could work for you, today's a good day to do so. iTechDeals has a discount on a universal magnetic windshield holder for Android devices. The MSRP is usually $19.99, although the going price for these kinds of mounts is usually less. However, it is reduced today to $3.99, which is considerably cheaper and even less than a cup of decent coffee.
Reviews seem overwhelmingly positive and shipping should be free on iTechDeals' website. So if you think you might need this, hurry up and grab one before they run out of stock.
