Also, I'm not convinced that resellers are all that free to cut the price below the MAP. Earlier posts in this forum suggest that Apple can apply pressure against this, perhaps by threatening to revoke the reseller's license with Apple? If Apple isn't trying to fix (set, control) prices, why do retailers have to resort to gimmicks like "we pay the tax special" rather than just being allowed to honestly tell the customer what their intended sell price is. Talk about a house of mirrors ...
Quite clearly, a manufacturer would run afoul of the law if they strong-armed retailers into selling at a prescribed price. As I mentioned earlier, retailers even find ways around MAP. However, if efforts to eliminate the "Dr Miles" rule are successful, then manufacturers would be allowed to set retail prices in a way which has been illegal since the demise of "fair trade" laws.
