I've seen a handful of people not have ads on their website, which keeps the website really clean and friendly but they'd sell an ad banner in their monthly newsletter. This is a very interesting idea, they all told me that their one ad used to pay for their entire month of costs and a little bit more, people would pay more as they knew users would open the newsletter and it wouldn't be blocked by any ad plugin like adblock plus. The users didn't mind it as they were still getting their information and "codes" to use for other stuff. It was a win win. Anyone thought about doing it?
