Our website sells themes that you only need to buy once, and they come with free support and updates that never expire. Normally, most websites charge a yearly subscription fee to cover the cost of updates and support, because WordPress and hosting require a lot of work to keep them up-to-date. Right now, we don't charge a yearly fee, but we might start doing so in the future to help pay for updates. We hope this makes sense and thank you for your understanding.
