Amazon is running one of its usual “Lightning Deals”. This particular sale involves a SanDisk Ultra 128GB micro SD card, which has received a small price reduction that brings it down to $16.99.
128GB plus the 32GB that comes with every Switch results in a total capacity of 160GB. That’s not huge, but it’s definitely better than having to try and rely on just the Switch’s default internal storage. And depending on the size of the digital games you get, that space may last you quite some time.
Since this deal is a “lightning deal”, it will literally only be available for a few hours. As of the time of writing, less than an hour and a half remains. Once it’s complete, the price will go back to $19.99.
