Where to Buy NordicTrack exercise bikes at Best Price
As you know, a price and buying conditions depend on the store where you place your order. Surprisingly, the official website is not the cheapest place to buy NordicTrack exercise bike (unless you are from EUROPE). Their orientation is to sold their equipment through large retail chains. We suggest you order directly from AMAZON. There you'll find better deals compared to the other websites.
