You should make it explicitly clear. Your thread right now is just an advertisement. "Use our website to get gift cards at a discount", etc. If it's actively in development and not yet 'commercial' per se then you should be making that clear in your thread, rather than making it one big ad. This section is for talking about your progress in development, asking for ideas, feedback on sections, where you are exactly, etc. It's not a section for only saying 'come check us out'.
