How we compare prices

Our reference is the lower of two 90-day averages: Amazon’s selling price and the lowest new-item marketplace price, using available history. It is not the previous selling price or Amazon’s Typical Price.

“Lowest price recorded” means the lowest Amazon selling price in the available tracked history, including matched lows. Our own dated observations are shown separately above when available. Neither comparison covers every seller, coupon or shipping charge.
