Network Tech via Amazon offers Prime members the GM Easy One Touch Smartphone Car Mount for $4.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $6.40.) That's $35 off list, the lowest total price we could find, and a very low price for such a device. It is compatible with most smartphones and features a removable, sticky gel pad base, telescopic arm, and 2-step locking lever.
