*Sigh* I don't know why it continues to amaze me that people fall for this crap. Maybe it's just the profit side of an abysmal education system.
(BTW: when you set up a web commerce site, there are higher rates for certain types: porn, gambling, and water filter scams. Interesting association.)
Just last month, I did an analysis of two identical water samples for some guy. He was furious and called wanting his money back. He knew one of the samples had to be different because he'd run it through his magical $3000 alkalizer. He needed his money back for something all right. But if he knew the results, why bother paying to have it analyzed?
Anyway, I'd better get busy and write a book about the health benefits of... um... let's see... putting a rock in your water tank. Yeah. Special rocks. And I've got 'em right here... for a price.
