At least, some of Amazon's pricing is dynamic. There must be an algorithm that decides the price. I don't know if it's still the case but we used to see used books sell in the thousands because algorithms would adjust the price automatically so it's not out of the question that it happens with regular products. BTW, the product is sold by Keen Footwear so whatever is happening might be initiated by Keen not necessarily by Amazon. When a third party is involve, Amazon is not involved in setting the price. They just make sure they get their commision on the sale.
