As its Gold Box deal of the day, Amazon offers up to 65% off select Samsung microSD and UHS SD memory cards. All items are eligible for free 2-day shipping for Prime members (free trial). Standard shipping is available for everyone at no cost for orders that meet or exceed $35.
Of course, these high-capacity cards are perfect for your Android device, DSLR camera, or GoPro but you could also get a bit more creative and use the microSD cards to add semi-permenant storage to your MacBook. The Apotop SmartSuite microSD Adaptor sits nearly flush with the side of your MacBook and is at its best price ever, just $16.67. The package includes three uniquely colored adapters and is compatible with the following Apple laptops: MBA 13″ / MBP 13″ / MBP 15″ / MBP 15″ Retina.
The Pro Series cards will get you increased speed over the Plus Series and are water/temperature/X-ray/magnetic proof.
