I find these prices for TurboTax Deluxe 2018:
Download from Intuit: 69.99 USD
Buy CD at BestBuy store: 49.99 USD
Why is the price of the CD and box apparently negative 20 dollars? Do I need to scrounge up an old computer with a CD ROM drive in order to save 20 dollars?
that appears to be the case. Intuit doesn't control what Best Buy sells their product for (and from another thread Amazon is offering the same price as Best Buy so Best Buy is forced to price match)
