You have to be careful of the search results. Even if you search for a specific model or part number it will give you random results. If you did not know what the part looked like you will buy the wrong thing. There also needs to be a way to put negative search terms with a minus sign to weed out the bad search results. I would like to be able to easily sort and filter results to buy items that are sold and shipped only and directly by amazon. For some items I would not want third party.
