For sale. Maybe. Depending on who you are. Who you are will also have an affect on the price.
If you are a so-called freaking "marketer"; An unbelievable high price.
Probably somewhere high up in the six figures.
If you, in addition to being a so-called marketer, also are an asshole; most likely 7 figures.
I don't know of any "marketers" that are not assholes.
An anti-spammer and depending on whether I (kind of) know you, like you and so on (including my mood, the weather and my stomach): From $0 and upwards.
You can try forsale in front of the a and then the domain name.

Anybody else: I have no idea. I'll probably keep it.
