We create & sell custom modules for OpenCart at extremely fair prices. Our modules are guaranteed to work with the default OpenCart installs that have corresponding version listings.
I make no guarantees that they will work with any customizations you may have already made to your cart.
There are obviously no refunds for any code purchased.
As far as why I charge for modules for an "open source" platform... I offer my code modules to work with OpenCart's code base. Code is like any other product. You use an open source cart to sell your "products". Just as we aew using OpenCart to sell my "products". It also ensures my guarantee on working code. I always keep my modules up to date with the latest version as soon as I can.
Support of future OpenCart versions
we intend to always keep my addons up to date with the latest versions of the core software. However, in the case where an addon is rendered unnecessary because of a similar core feature or when a module turns out to be more work to maintain than it is worth, I may choose to discontinue support for it. These are rare and unlikely conditions. Typically in the case of a discontinued item, a viable replacement is created, and this replacement may or may not be available to previous purchasers of the discontinued mod for a discounted price. In most cases, upgrades to future versions are included with the price of the initial purchase.
