Yea, me too SW. It's aggravating.
FYI, many vehicle dealers use software called Matrix (or similar) to determine parts markups. Matrix applies multipliers based on many factors (considered proprietary), to calculate a selling price. Cheap parts get a much higher markup that major parts such as short blocks, for example. So you may be buying a bolt that costs the dealer $1.00, has a list price of $2.00 (which really should be the sellng price) and Matrix calculates a selling price of $4.00. If you ever open a wholesale account at a dealer, which I commonly do, you have to be careful of how they compute your price....25% discount from Matrix, 25% discount from list, 20% above dealer cost, etc., which can be vastly different.
