Founder and general manager Nathan Weathington wants the free online classified site to be ''the home of the deal''.
So whether a million-dollar home or a luxury vehicle, an oven mitt or a pen, or even a former church, the range of items listed was the part of the business that fascinated him.
Mr Weathington described Post a Note as a New Zealand version of Gumtree or Craigslist.
It operated like a traditional community board, for people to buy and sell items free in their community.
It did not charge users to buy, sell or browse the online classified site and that would never change, he said.
Post a Note had outgrown its original site and a new site was recently launched. He was both excited about the future and confident of the venture's success.
''This isn't something new. This is the classified business. This is the future, no doubt about that,'' he said.
American-born Mr Weathington's own career has also been somewhat fascinating. Or, as he puts it, his resume could be seen as a ''dog's breakfast''.
He grew up in the small rural town of Bremen, Georgia, in the south of the US, and completed a bachelor of civil engineering degree.
While teaching maths in the Bahamas, he met his future wife, Morgan, and followed her to Canada, where he did an MBA.
He started working with his father-in-law, David Black, of Black Press Group Ltd, a large privately-owned media company, publishing newspapers in both Canada and the US.
The company's classified revenue was being affected by a free classified site and it was decided to buy a small company, which Mr Weathington was involved with turning into what was, at one point, the largest free classified site in Canada. At one stage, Used.ca had four million users.
Mr Weathington also became involved with running newspapers and, when some spoof horoscopes he was writing for one particular publication proved popular, he was offered a book deal.
That led to Where The Hell Were Your Parents? - which was based on his childhood and which he described as a combination of Stand By Me crossed with the Dukes of Hazzard - and Invasion of the Bastard Cannibals, which recently won an independent publishers award in humour.
Six years ago, both Mr Weathington and his wife were looking for an adventure. He wanted to go fly fishing and she wanted to become a midwife.
''For me, I'm a pretty onedimensional guy. If I can fly fish, the rest is detail . . . I moved a family of four over the Pacific Ocean to go fly fishing. That's insane,'' he said, laughing.
Before that, he knew opportunities existed in New Zealand for a free classified site and so, on arriving, he launched Post a Note.
In 2014, Allied Press, publisher of the Otago Daily Times, took a majority stake in the business.
The Weathington family is now happily settled in Wanaka, where Mrs Weathington works as a midwife.
And Mr Weathington manages to indulge his love of fly fishing, even getting tennis elbow from fishing too much.
