Try selling a phone that is over $1000, fees last time i did this was almost $100 (85 + listing fees).
I don't really like trademe to much anymore as you list something and all you get is "swap for this thing that is less value than what you have" or "can I make payments" or some very low ball offer.
I even had someone argue with me about how he does not think I should be asking the price I am because I rejected his low offer.
Also people are just rude on it like "$450 buy now" or "I'll only pay $450" when its listed for $800.
I now also notice more people leaving phone numbers to deal outside of trademe as they know the seller charges more to cover fees. The seller is more willing to accept $1000 buy outside of trademe rather than $1100 on trademe which might not sell due to the higher price
