Yes that will work. You can buy the package with the 16 digit License Code anywhere. There was one user who only bought the CD for $10 but didn't know she also had to buy the version and License Code separately. If you buy in the stores be sure you get the full package. Some places like Costco & Sam's you have to go to the pickup window after you pay to get it. Oh and if you buy Deluxe in the Stores it can come 2 ways, Deluxe with a State and Deluxe without a state for states without an income tax. So check the box closely.
