Amazon offers its Prime members the iOttie One Touch Universal Car Mount, model no. HLCRIO102, for $11.99 with free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, shipping costs $5.29.) That's the lowest total price we could find by $5, although we saw it for $2 less during the week of Black Friday. It features an extendable, adjustable arm that accommodates most smartphones.
