You might get a better price from a reputable online seller that carries TurboTax Business. But if the price is extremely low it's probably a scam of some sort - pirated, malware, etc. Stick to the well-known major online sellers.
When you say "business edition" do you mean TurboTax Business, or do you mean TurboTax Home & Business? They are different products. Make sure you are getting the right product for your needs.
Is TurboTax Business right for me?
