The problem is, however, not the price - but rather a big demand issue, or lack thereof. Such a site is informational, and demand is low for these. Specifically a sales oriented magazine? Even worse.
Set a price and that's it. Not a high one. If not sold, I'd not renew it.
Edit: If it was AI Magazine or even Crypto Magazine... then yeah, it would have been a different amount and a different chance of sale.
