People I respect have argued on both sides of the BIN price vs Make Offer debate. As has been mentioned, I think it probably depends on the type of name and the price point.
A BIN is far more likely to be a spontaneous purchase if it is priced in that range. Once a potential buyer delays to think more, look at more names, etc. there is some chance of losing the potential sale.
On the other hand by stating a BIN price then it may well result in losing money you could have made. In addition, there may be cases where because the potential purchaser thinks the BIN is way too high, or way too low, they don't follow further and you lose sale.
I know Rick has argued the PUR route, I guess the idea being twofold one that it adds some sense of like premium real estate that you have to talk to the agent to get a price range, and secondly that price might be adjusted according to intelligence on the potential buyer. Both of these arguments make sense, but maybe only for truly strong domain names.
I once had virtually all of mine BIN priced. Currently I am trying a mix, but most still have BIN pricing.
Thanks for poll, and to all who have responded.
