Amazon offers its Amazon Prime members the Altec Lansing BXR1220 Computer Speakers for $11 with free shipping. (Non-members can get free shipping on orders of $25 or more; otherwise, shipping adds $8.87.) That's tied with last week's mention and the lowest total price we could find by $5. This USB-powered speaker pair features shielded speakers, built-in controls, grille cloth, and more.

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.)
