Just buy the game from the NIB buyer who flips the game in under 6 months - then prices are what you negotiate
The reason for these kinds of 'minimum prices' are to prevent a 'race to the bottom' in the channel. They are distribution models to protect the dealers from facing unrealistic pricing pressure from other dealers.
If the manufacturer expects dealers to provide A, B, and C... dealers have a reasonable expectation that they will have enough margin and market protection (territory, controlled distribution, or other things) to do that and be successful themselves. If your channel is not healthy... you can't be either.
These models are intended to keep a dealer who decides they can live on unrealistic margins (by cutting services, not doing what is expected of them, not building a sustainable business) from disrupting the market by offering games at prices that the channel as a whole can not sustain. Random joe starts undercutting everyone... and everyone in the channel suffers either due to lost sales or trying to keep up. Ultimately the channel is weaker, they don't offer the services that the manufacturer leans on them for... and if uncorrected, dealers fold, distribution suffers, and customers end up suffering because the manufacturer isn't offering the direct services... and the dealer network isn't there either.
It's not so much about 'more profit' - its to ensure a healthy enough margin so that the channel partners can actually succeed and hence both parties win.
