Saving on laundry detergent?

Saving on laundry detergent?

I stumbled across these laundry magnets and was wondering if anyone else had heard of them. If they work it'd be great, but site doesn't go into any great detail as to how they would work. It just references other early scientific research (which I plan to research myself), and offers a list of testimonials. But it has me curious about something. If it really is just that magnets at opposite sides of the tub work to get the clothes clean, couldn't we just go to Lowe's and buy a couple for a few dollars rather that spend $50 from this site? I really like the idea of saving money and helping the environment, but I'm just a little skeptical of this one. Anyone have any feedback on it?
