Pacchetto gratuito per WIX Premium Partner

Hello everyone, I have a request. Would it be possible to have a free or complimentary package to test a fully functional prototype, in order to better understand certain features? I often find myself wanting to test systems, applications, payment methods, and other services to ensure I select the most appropriate solution for my clients, but this is not always easy. Sometimes I spend a great deal of time researching, and I don’t always find detailed information. Before I can properly use an app to meet a client’s needs, I am required to purchase a package, which is not always the right solution and does not seem professional to me. Perhaps there is an alternative or a better approach, but I am unaware of it. Thank you very much for your feedback. Best regards, René
