Agreed Amazon isnt the most reliable, but as I said, I corroborated this at a few other stores. Costco generally has fixed markups for its products (15%), as does Trader Joes. The fact that you haven't seen price fluctuations there aligns with my conclusion that the price volatility isnt being driven by increases in the cost of goods, but rather retailers who think they can trying to increase margins.
