Earlier quoted context omitted.
How is that? If you buy an engine, do you itemize by: engine block, alternator, water pump and starter? You might include in the requirements that the engine must come with all 4 extra elements, but you will pay for the whole engine. Now, if someone wants to be misleading, they could say the water pump was 1/4 of the price...
If the total R&D cost for all items is split across every single product equally, there's no way to tell how much of the $435 hammer is R&D for the hammer. It's a really weird way to do accounting, almost like they just didn't keep track of how much R&D they did for each item. And that makes you wonder if the amount they are charging is even real in the first place. In general it lowers confidence and makes you think…
so what? Like another commenter has said, you bought the package, it's not your business how much each individual piece is actually worth. You pick the best bid and move on.
