If you purchased a download, you likely should have gotten an email with the special download link and a license code. At least that's the way it works at Costco. In fact, Costco uses 2 emails. First Costco sent an email that the order was fulfilled, then "some" minutes later a second email arrived with the download link and license code. I realize that Sam's may fulfill its digital orders differently, but the principle ought to be the similar. The license code is used during installation to activate the software.
