I mean the traditional manufacturer->wholesaler->retailer link is now evolving to include the scalper at the end of it. They need to mark up the prices to earn a tidy profit from their work. People should be grateful they have the opportunity to buy from them. It's not different than going to a retailer over a wholesaler.
Depends on how they got their hands on the product in the first place. Pisses me off with stuff like concert tickets, where resellers have the opportunity to buy before the general public. I want to resell at ticket and round up to the nearest dollar from face value? I'm a dirty scalper that they go after. Another place gets to sell it at five times face value, and hey, that's cool, he's a business.
The ball is round, the game lasts 90 minutes. That's fact. Everything else, is theory.
