Amazon is featuring the PDP Rematch Glow Enhanced controller with a unique pink Princess Peach Mario Kart theme at a discounted price of $39.99. While it is not the deepest discount we've ever seen on a product, this is the first time Amazon has reduced its price from the already fairly affordable $44.99. For gamers who've been looking for a great Switch Pro controller with epic Mario Kart-themed graphics, this is an excellent opportunity.
