I simply refuse to pay full price for any of these retro mini consoles, so when they dip down to 50% off or more, I start to take notice and make purchases. If you missed Best Buy’s recent sale, the Sega Genesis Mini just hit my personal price point of $39.99 at GameStop. These are no longer in production, so once these sales run their course, eBay and Facebook Marketplace will be your only common options.
