Well done for sticking with your gut assessment and passing up a bargain - greed too often overcomes good sense.
Item:
Geektastic: Just report your concerns to Trade Me.
On what basis? I haven't been scammed and I don't have anything other than vague speculation that the seller is doing anything dodgy. His track record suggests he has plenty of happy buyers in the last few years.
You don't have to be scammed before you can report a listing or a trader. Sometimes you will be doing a public service.
I've seen Trade Me remove listings or block traders due to false statements, suspected stolen goods, suspected fraudulent activity e.g. listed item does not exist, hacked accounts, and underage users e.g. child using parent's account.
Trade Me also has access to a lot more information than you have about the seller and their behaviour. The most obvious advantage for websites is that they can see IP addresses and can track patterns of behaviour.
In your case, the trader is probably not entirely truthful in their description and may well be breaking the law regarding their income and tax status. Either fault is sufficient to break the Code of Conduct and the Terms & Conditions:
