Amazon is offering MacBook Pro/Air’s Twelve South BookBook V2 for $55.99. That’s $24 off the typical rate there and the lowest price we’ve tracked is within just $4. In addition to protecting your modern MacBook Air or Pro, this genuine leather case also gives it a retro look and feel. A hidden pocket resides under your MacBook base, giving you clean, organized space to store some paperwork. 4.2/5 stars rated.
Consider Speck’s SmartShell Case for MacBook Pro at $33 if you’re just looking for an extra layer of protection. Over the years, having owned several of these, I found them super protective without adding a lot of bulk.
