Parking/Selling domains through DynaDot

This question is mainly for those who register domains with DynaDot. If you look inside the settings for the domain they have a “for sale” option…Apparently, if you park the name with them you can have a little “But this domain” button above your parking ads.

Has anyone ever sold a domain this way before? Has anyone had good payouts with their parking ads? It looks pretty similar to Sedo landing pages as you can see from the screenshot below. How do payouts work if you sell the name? Is it only account credit like parking payouts?
