Hello Alexandre,

Many thanks for your interest in our product. I am Vincent form Customer Service Department at Cmsmart.net. It is my pleasure to support you in this case. Please find my answers as below:

1. About the Online Design Plugin, we offer 2 kinds of payment for premium version:

+ Auto-renewal: For this type, you will pay 150.69$ for the first payment to get 6 months of download, update and support from us. After that, you need to pay a recurring fee at 24.69$ to extend more 6 months of download, update and support. Also, if you don't like to pay recurring fee, you can cancel it. In this case, you still can use our plugin forever.

+ Standard Payment: For this type, you will pay once at 161.24$ to get 6 months of download, update and support from us. After that, if you want to extend more support, download, or upgrade, you need to buy our product again at the first price (161.24$). This case, you still can use our plugin for lifetime.

You are recommended to choose the auto-renewal based on my experience and our customer's :)
2. I'm currently using the free version (1.7.0) and the available paid version is 1.8.0. I can't hide the "add to cart" button prior of creating their design. Is it still an issue in version 1.8.0?
=> Don't worry, the version 1.8.0 there was no problem with the issues you mentioned. Our dev fixed that issue for version 1.8.0 already.

If you have any questions, feel free to let me know
Best regards,
Vincent
