This is a business that is known for, and relies on finding somewhat scarce material (salvage) that they must laboriously and carefully remove and store. Because of their fame and notoriety I'm sure that they have to pay through the nose for everything they get. They have lots of employees, and a huge piece of real estate. I can't guess how many customers and fans must come through their establishment everyday. Can you imagine how disappointed their fan's would be to travel long distances and show up to an empty warehouse? Their business relies on having lots of unique hard to find items to fill their shelves. Even if they have a ready endless supply of freshly milled and dried lumber, they have to mark it up just to stay in business. I see the business as more of a museum than a retail store. They can only mark up their t-shirts and candy so much. Their average customer doesn't know how much lumber costs.
