This Kobra Bluetooth OBD-II car code reader is down to $8.03 on Amazon with code UKLW9NL5. This is the lowest price we've ever seen, even through previous coupon codes. It has sold around $13 for several months now.
This reader does not work with iOS devices. If you need one for your iPhone, this Kobra deal from the end of March is still active. It's not Bluetooth, it's Wi-Fi, but it works with all three platforms.
