I have hosted deals.habitate.io, where you can submit your Black Friday deals in the relevant channel.
On 26th and 27th, I will invite more viewers from my email list, network, friends, and customers to upvote favorite deals and comment on any questions that they might have for you. (Might go ahead and submit on Product Hunt as well).
It's completely free, with no paid promos for any brand inside the platform.
So far, companies like GanttPro, BetterProposals, accordably.com, soar.sh etc. have submitted their deals and more to come. This could well turn out to be a promotional campaign for what you are building and get you some feedback along the way.
If you receive any comment, you will receive an email notification to reply.
This is not the full-time project I am working on; I just wanted to host a free, open platform for everyone to post their promotional deals and get some exposure along the way. I also wanted to make full use of my product habitate, showcase the product abilities, and learn something along the way.
Let me know what you think of it. Open to hearing any feedback or comments.
Meanwhile, if you are thinking about creating some discounts on your product, this article from mailshake might help you.
