Amazon offers Amazon Prime members the Toshiba 14" Notebook Sleeve, model no. PA1490U-1NCZ, for $4.25 with free shipping. (Non-members can spend $25 or more for free shipping; otherwise, shipping adds $8.54.) That's a buck under our July mention and one of the least expensive name-brand sleeves we've seen. (It's also a current price low by $16.)

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.)
