I think Afternic is worth it, but I just changed all my domains back to basic promo from extended promo. For the extra 20% commission and having to list a BIN price, it hasn't been worth going with extended promo - the thought is your domains get more exposure but I haven't noticed a difference myself. Also, there have been a few examples lately on the forum of good xx,xxx sales from negotiating, so why list a BIN price anyway?
