Free open source – limited support
We created these additional extensions to facilitate our own and our customer operations. They complement Magento functionality to enable our customers use it instead of other specialized storefronts. We released them as free Magento extensions for everyone to enjoy and benefit.
In other words, if you are not a genuine ZetaPrints customer we cannot help you with any issues your individual Magento installation has. You will need to hire a skilled Magento programmer or do it yourself.
Please, do let us know about any problems you encounter. It could be a bug in our code which we would like to find and fix.
