I’ve been asked about listing domain names for sale with Buy It Now prices on multiple venues. For nearly all of my inventory quality domain names, I list them on Afternic / GoDaddy and on Dan.com with buy it now prices. I know many other investors also use marketplaces like Sedo, Epik, Efty, and a few other venues as well.
A concern I have had is that a domain name will sell to different buyers on different platforms. While this may seem unlikely, it is easy to imagine a scenario where this happens. For instance, a phrase might become a social media hashtag, and before a domain owner can update pricing or remove sales listings to reflect the growing popularity of the phrase, buyers utilize the buy it now option on multiple platforms.
