All of our Legacy or PRO license holders may upgrade to a Premium edition at any time. The cost is the difference between the $99 Professional edition and the $149 Premium edition. So for a small $50 dollar fee, you can open access to our members area where you will download all our external apps + easycart extensions.
If you are new to EasyCart, you can purchase a new Premium edition license and get started in our members area. Only Premium edition users have access to our external apps and EasyCart extensions that we build.
