How to make money from selling Star Trek memorabilia

Evidently the way to make money from selling Star Trek memorabilia is to sell a lot of CDs that are supposedly about selling Star Trek memorabilia. There are more than 40 listings on Amazon for audiobooks published in 2007 about making money from Star Trek memorabilia.

Here are some of the titles:

• Successful Sales Strategies For Selling Star Trek Memorabilia Online
  
• How To Sell Star Trek Dolls Online With Absolutely No Inventory
  
• Learn the Star Trek Memorabilia Online Business Godfather Principles
  
• Star Trek Memorabilia Internet Business Building Bootcamp
  
• The Secret Make An Extra Income, Success Principles and Biz Networking for Star Trek Dolls On-line Businesses 3 CD Course
  
• Unraveling The Inner Game To Star Trek Memorabilia Sales Success Online
  
• The Techie Stuff: Setting Up Your Star Trek Memorabilia Online Storefront
  

All of them sold through but not by Amazon. It looks like they're all basically the same thing, judging by the one negative comment posted, with probably no Star Trek-related content at all:

1 out of 5: "the disc received was how to start a web business and had nothing to do with the title given"

Seller Response: "We wished that you had contacted us about your order. You ordered, "Earn Extra Money In Your Spare Time Selling Overseas Outsourcing Services On-line". Selling anything online *is* about starting a web business."
