The best checkout module ever for opencart...extremely beautiful, simple and easy checkout process. I have never come across any checkout modules like this for opencart...I want to say, all One Page checkout modules all over are all the same...i personally dont like those but have no choice but to buy to replace the default checkout page.
Overall, since this comes with complete checkout framework which makes it stands out from the others.
Excellent Support and quick fix to a small customization required..completely love this module.
