I found a super deal for Precor online, but it's from a company(dealer) that I don't know and is not listed on your website. Are they legitimate?

Possibly not. We sell through Precor Authorized Dealers, Precor.com and directly to Amazon.com (not through 3rd parties on Amazon.com). To find out if the Dealer is Authorized, go to our Store Locator and type in the zip code. If the seller does not appear in the list, they may be an unauthorized seller.
