How to interpret the price trend graphs:
Thick black lines represent the average price for parts in the given category. Gray banding represents the minimum / maximum price range. Individual part prices are displayed as light blue points within the gray banding, creating an intensity graph of the price distribution. Dips in the lower price bound typically correspond to sales, or in extreme cases merchant pricing mistakes. Price data includes promos, coupons, rebates, and shipping costs (when available).
