usually I just attempt to trade random stuff I don’t need that suits their stat build
or is a popular item
Trading is best when both parties get what they want within reason imo. The moment that within reason is passed is the moment when one side overpays by a lot while the other profits from it.
This for example would be completely outside of reason since if you did even a little research you would come to know that you can get offers 100x better within at most an hour
Other than that, smaller stuff like offering an acri for a ssword is still an overpay from the ssword side but id consider that a trade if both parties are fine with it
