It does, but they don't actually do anything about it. Hundreds of people have been reporting people selling Ring Fit Adventure for hundreds of dollars, but Amazon is still letting them do it.
But FWIW, you click 'Report incorrect product information', then 'Other product details' and 'price issue'.
I just noticed that link the other day and wondered if it could be put to good use. They certainly don't make it obvious, but maybe that's part and parcel to ignoring it anyway. :)
