October 10: GameStop and ThinkGeek are both receiving more SNES Classic Editions. They'll be sold individually in stores beginning today, while bundles and standalone units will go on sale online on October 11. Specifics regarding the bundles were not shared, and it may take a day or two for retail stores to actually begin selling their micro consoles.

October 5: The SNES Classic Edition sold out at release as expected, and prices were high on Ebay, but Nintendo has insisted the system will be easier to get than the NES Classic. Your next opportunity to get one is now here, as GameStop has the micro console in stock on its website right now. As always, there's no telling how long it will last, so act fast if you're interested. [Update: It looks to now be out stock, but it may be worth refreshing the page today just in case.] We'll report back as the system comes back in stock at GameStop and elsewhere. In the meantime, check out our SNES Classic review.
