If you're like me you can never get enough memory for your consoles. Amazon has a pretty good sale going on the Deal O' The Day :
Gold Box Deal of the Day: Up to 50% Off Transcend Flash Memory Cards, External Hard Drives, and Solid-State Drives.
$16.99 for a 32 GB card for the 3DS is good deal. Anyone try the Transcend 32GB MicroSDHC Class10 UHS-1 Memory Card with Adapter 45 MB/s (TS32GUSDU1E) on their 3DS? I normally use the Transcend 32 GB High Speed 10 UHS Flash Memory Card (TS32GSDU1) but the Micro + adapter might be more versatile for other things.
