any thing similar ,
may be a wallet that generate an address to every seller or send their commission automatically
Never heard such service or marketplace where you can sell stuff and give an affiliate link to someone for commissions?
I think if you are going to promote or sell something online why not make your own website/landing page with WordPress and use Blockconomics plugin for your payment gateway.
Because you can use their service called "Payment Forwarding Service" it looks like this image below.
Where you can set manually how much bitcoin do you want to forward automatically. Never tested this Payment forwarding yet so much better try to ask this user
btc_enigma about this.
Or make your own WordPress sales page and hire someone to promote your product with their unique link/unique sales page and manually pay them for their commission every week.
It's just my suggestion but if you have other purposes looking on some sites that offer "auto forwarding commission." well, I already tried to search on Google but I can't find any service like that.
