I'm currently testing this solution and I'm delighted, it's truly a diamond that still needs a little polishing and I'm very happy with the development plans visible in the roadmap and I hope they will be available for sumolings. It's great that you can use flash sales with a visible timer and bump offers. I'm impressed with the speed and quality of support; I asked about the Polish language, and a few hours later, it was enabled in my store. A few minor things that could be improved at this stage of my testing concern the UX. When something isn't visible because the user hasn't done something or configured it incorrectly, a negative perception arises that it's not working. For example, in the case of flash sales, products aren't visible if the "pay what you want" feature is enabled. Of course, after a moment's reflection, this makes sense. At the same time, I think it's worth adding a short explanation, e.g., "flash sales only work on paid products with a specific price." This should improve the learning curve. Especially when you often leave certain options enabled during initial trials.
In my opinion, this is one of the best products on appsumo, and at a good price. Congratulations to the owner and the entire team. I'm currently developing the first campaign for the new product, and within a week or two, I'll launch a campaign selling my training through Zylvie and probably will upgrade ma tier.
