JR: I have to reject most of your post as non-responsive.
Your competition is anyone else your potential customer is willing and able to buy from. Whether or not you CHOOSE to compete with anyone else your potential customer is willing and able to buy from - but they are still your competition, as far as the customer is concerned.
Right....so the products and services you offer will still be available if you go out of business, it's just a matter of who will be offering them.
If a customer offers you 10% over wholesale, when they can buy it at 5% over wholesale, I'd say the customer as advanced toward the middle ground. Now, if you want to argue where the middle is specifically - that's a different issue.
But I am! Globalization, baby!
On one hand, I understand volume discounts. Intuitively, it makes sense. On the other hand, I don't get it, and it doesn't make sense. If a manufacturer has the capacity to produce and deliver 1 million widgets per year, then it should not matter HOW the sales are distributed, let alone discount based on volume. If the world wide demand is 1 million widgets per year, and they can make $100/each without a discount and sell them all, they make $100M. If they discount half of them by 20% due to volume discounts, then they only make a fraction of that. This makes no sense. NOW - if the theory is that by selling such a high volume (through whatever means), then a dealer can INCREASE demand, and thereby improve manufacturer profits, a discount is merited - but ONLY if the discount encourages the dealer to do whatever it is doing to increase demand (in this context, probably selling at a lower price). As I write this, I'm seeing all kinds of ways for this to get more complicated though.
