.nets are not as liquid as you think, look at the difference between liquid 3 assets and .com, especially 3 letters, winner godaddy on this one. If an end user with an existing business it great, if a investor looking to slip, then they have their work cut out for them.
I think it's just the fact that vape is such a massive industry. It's like casino, sex and anything in the top sector. Those domains will sell but I would not go on a buying spree of .net expecting similar results.
couple weeks ago I got yet another offer on GD for vape.ws
Yes ...the ext is basically do do...BUT "vape" is such a powerful in demand market and it's a nice single 4L word....as I've told many others my faith in this name is that the .ws can also stand for "World Shop" or "World Supply/Supplies" if enduser wanted to brand/ advertise it that way.
