If you’ve had bad luck so far in trying to nab an SNES Classic Edition, you’ll have a fresh chance tomorrow. Two major retailers have announced they have stock in hand and will be selling it starting October 11.

GameStop and ThinkGeek will both have undisclosed numbers available for sale online and (at least for the former) at retail locations. Look for them starting mid-morning Pacific time.
