Amazon has slashed the price of the Asus TUF Gaming M4 Air gaming mouse by 30%, lowering it from its regular $49.99 to $34.99. This discount translates to a savings of $15 for customers seeking a reliable gaming mouse that punches way above its price class. In an already very reasonably priced gaming mouse, like the M4 Air, savings of $15 aren't available every day. In fact, this specific mouse hasn't seen a price as low as $34.99 in at least 30 days.
