If you purchase a license directly on the Tracker website, you can log in to the customer page and purchase plans at discounted prices, such as upgrades or extended maintenance periods, depending on the status of your license at the time. I am well aware of this because I purchased my license directly from the Tracker website. This pricing strategy is one of the attractions of the PDF-XChange Editor.

Incidentally, according to Jungle, one of the authorized resellers in Japan, "the single-license BOX/DL version is granted a one-year update service period after the activation key is activated, but this period cannot be extended." They also explain that "if you want to use the latest version after the expiration date, you must purchase a new single license."
