CTCStore offers Amazon Prime members the Acase Faux Leather MacBook Air Cover in Black for $17.95. Coupon code "FW6SCWEN" cuts it to $10.95. With free shipping, that's $2 under our mention from Cyber Monday and $2 under the lowest total price we could find for a similar item elsewhere. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $8.61.) It claims to fit the Apple MacBook Air MC969LL/A. Deal ends December 5.

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.)
