Then, I turn around and sell the item on ebay for an average profit of $11.91 after shipping and taxes per item.  
In all, I average about $12 of profit for every 11 minutes of work on rebates, but there are not always mail-in rebates to do. I also am not including the time it wrote for me to write a script to keep up with the rebates or find them to begin with.

 He's also not including the time spent on eBay, which appears to be where he is actually making the profit. The rebates themselves are (except for occasional bonuses where, for example, they rebate the MSRP on a sale item) just getting back cash already spent.
