Nintendo Switch - Joy-Con (L/R)-Neon Red/Neon Blue - $ 64.59
Rakuten had this for $63, but is now sold out in this Red + Blue color combination.
Amazon also has the Gray ones for $68.96
PS - B&H Photo has the same price as Amazon for the Gray ones, but was unwilling to do so for the Red/Blue ones when I live chatted them. But if enough people ask, maybe they will reconsider.
