So, I'm in the market for a new bike and am looking to stretch my dollars as much as possible. One site I've stumbled upon is Discount Mountain Bikes | Mountain bikes sale | Cheap Mountain Bike sale. I have no experience with them. They appear to have some great deals on slightly older (2-3 years) bikes. Does anyone have experience with them? Any gotchas I should know about? Thank you in advance for anything you can tell me.

EDIT: Sorry, I pasted the URL but apparently it gets converted. If it matters, it is (discount-mountain-bikes dot com).
