Afternic DLS (With FT) brings your domain in the reg path of GD and ~100+ other registrars (I don't remember the correct registrar count atm). This is very similar to the GD prem listing but with other registrars also. One key difference though is that GD Prem listing price that is set by the owner is what is presented to the "searcher/buyer". In the case of Afternic DLS listing, some registrars markup the BIN price by up to 15% when presented to the buyers. This additional 15% is pocketed by the registrar themselves. This can be a negative depending on how you look at it.
