It's not really any different from wholesale vs retail, of course a seller would prefer higher volume higher margin customers over lower ones. That is in no way scalping as defined. Just because you're not a high volume customer does not mean you are getting scalped. It's like saying because Sysco doesn't sell directly to you and only to restaurants that the restaurant is "scalping" you when you buy their food. Your explanations really are not very convincing because the behavior you're describing is how wholesale works in any field.
