This was my initial thought, but I believe it says not to advertise excessively there. I don't plan to post more than one thread, but I couldn't tell whether "Excessive advertising" meant I could have my salesthread there or if the sub is only to be used for updates to my product.
The board mentioned above is to be used for the announcement of your project where users can discuss it and share their opinions about it. You use the ANN thread to post updates as well. But not to use it as sales-thread.
As for managing sales, it depends on the paiement method you are willing to accept; if you will accept bitcoin or other cryptos including bitcoin, then you should start another topic in the
Services board or in the
Marketplace main board. If you will only accept altcoins, then the apropriate board for a sales-thread is the
Marketplace(Altcoin).
Don't forget to read pinned threads in the top of the board you will choose.
