2Go Products LLC via Amazon offers Amazon Prime Members the 4-Port Octopus USB 2.0 Hub in Black for $5.95 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $8.24.) That's the lowest total price we could find by a buck.

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.)
