Amazon offers its Amazon Prime members the NAVGEAR Universal GPS Car Vent Mount Holder
, model no. 14027, for $2.30

. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's a slight drop from our September mention and the lowest total price we could find by $6. This mount attaches to the air vent and adjusts to fit most GPS units.
Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months. (Note that currently there's a waitlist for Amazon Mom.)
