Amazon offers the Nintendo Switch Joy-Con Pair in Gray, model no. HACAJAAAA, for $70.81 with free shipping. (Jet.com charges the same.) That's $5 under our January preorder mention and the lowest total price we could find today by $9. Both Joy-Cons can be used independently in each hand, or together as one game controller when attached to the Joy-Con grip. Each Joy-Con features an accelerometer and gyro-sensor.
