But costs are different, so that seemed like it would harm the ability of small businesses to compete? Wouldn't it be better to have a 'most favoured nation' deal where the cost of the book to a supplier (from the publisher) is fixed. That seems like it would create better competition? I can pay more for better service, for example.
