Hank,

>Let's say the average garage sale item is $2, and can be sold for $4 on ebay. So the first week is 5 items. With the profits, you can buy 10 items the next week, etc. On the final week, David will have to buy somewhere between 400K and 500K items and then sell them. At 10 minutes per item to list it, handle inquiries, and pack it, that will amount to 5,000,000 minutes, or about 8,000 hours, which will be hard to pack into one week. <s>

But with a Million dollars on the line, I can afford to hire a few temps at that point. :-)

Or, maybe at $1,000 I switch to used cars instead of garage sale items, then foreclosed houses, etc...

Anyway, it might not take that many garage sale items if I do as well as I did today. I picked up several books for $1 or less each, that usually sell on Ebay for $20 to $50 each:

• Golf is My Game - Bobby Jones, later printing, but in same year as first ed.
  
• Easton Press edition of Moby Dick
  
• True First Edition of Pat Conroy's Lords of Discipline (at least $50).

A few I passed over, however :-)

• Seven Strategies for Wealth and Happiness
  
• How to Build a Fortune in Real Estate
  
• The Joy of Working
