Last week I had two people try to scam me in trade on higher end items, both using the same method (2 different people though).
Here's how it worked both times.
They opened trade with the proper amount of ectos and gold for the item and then rather than trading, they canceled. They pm'd me oops sorry and opened trade again with the wrong amount of ectos and when I pm'd back saying that's wrong, they changed the offer again to the right amount of ectos and dropped the gold from 100k to 10k.
Of course, I pm'd back saying 100k not 10k and then


One instance took place in GTOB for my EL Cerebral tonic and the second instance was in Kamadan for my Tormented Staff.
Watch the trade windows carefully, the scammers seem to be out in full force but those suckers didn't get me
