Welcome to Opencartpowered.com. My name is Greg and I'm an Opencart extensions developer based in Poland. Feel free to contact me for support - if you've bought one of my extensions or if you're looking for a functionality that does not exist - I may have a solution for that.
Thanks for looking here,
Fully tested extensions
My extensions are tested to work on clean Opencart installation before uploading to Opencart's Extensions site.
If you wish I can help you to install my extension totally for free (assuming you're using default Opencart instalation where no modifications are necessary)
