Because it will in all likelihood break before it ever arrives at your door.
I have purchased a fair number of items from DealExtreme, and have never had the slightest bit of trouble with any of them.
I understand that when I buy a multi-meter for
$13.66, I am not getting a tool with
Fluke robustness and quality, but I am also not paying $430 for it! I set my expectations appropriate to the price, and have
never been disappointed. I am quite pleased with my DealExtreme multi-meter, which actually has more features than the Fluke meter linked above.
