CTCStore offers Amazon Prime members the Acase Faux Leather 11.6" MacBook Air Cover in Black for $9.75 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $8.61.) That ties our December mention and is $8 under the lowest total price we could find for a similar item elsewhere. It claims to fit the Apple MacBook Air MC969LL/A. Deal ends February 3.

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 there is currently a wait list for Amazon Mom.)
