Found this whilst looking for retropie controllers to set up a retro console for the kidlets, seems to be a good price, $79 elsewhere.
Also found the Pi400 for $109 plus $7 shipping or free CC at UMART:

The 8BitDo SN30 Pro G Classic is a retro controller with a full range of functions. It has a complete set of buttons with clickable joysticks, vibration, gyro sensor, Bluetooth, rechargeable battery, home and screenshot buttons and a USB-C port. Not to mention a proper D-pad. 8BitDo controllers are designed to be as versatile as possible with any modern device. So you can easily couple the controller as an X-input or D-input device via Bluetooth. With the supplied cable you can even use it as a wired USB controller. 8BitDo also regularly updates the firmware for extended system compatibility such as Switch, Raspberry Pi, Retron5 and more.
Really solid controller, I've had mine for a while now and been really happy with it.
