The Mini SNES was only available from EB Games this morning when Nintendo announced their new system to the world. But good news - they're not the only retailer, which is handy considering the console won't be available after 2017.
JB Hi-Fi is now taking orders on the Mini SNES as well, and much like EB they're limiting shipments to one per customer. They're also a little more explicit than Nintendo was in their release this morning, noting in bold that "an AC adapter for the USB cable is required to play the system but is not included in the packaging".
So all up, you'll have to spend $138 plus $6.95 for delivery. But if the EB Games site crashes, or they run out of stock, it's good to have an alternative. Here's the direct link for the USB AC adapter as well.
