I'd take any one of these discounted retro 8BitDo gamepads over any other Prime Day controller deal you might find today
8BitDo Pro 2 Bluetooth | Bluetooth & USB-C | Rechargeable battery | $49.99 $39.99 at Best Buy (save $10)$10 might not be a massive discount, but that's a 20% saving for a controller that was already just $49.99. This is my personal favorite controller, and I don't see that changing any time soon. It's incredibly well-built, feels satisfying to use, and brings tons of nostalgia despite being modernized in all the right ways.
