If there is something you want that is on the Trading Post and the cheapest price (by a LOT) is from someone who has only been playing for a week, do you buy from him/her?

In this particular case that's the only valuable item the person has. The rest of the stuff in her shop or in trades is of the 5,000 NP or less variety. I've seen some n00bs who have a dozen or more unbuyables -- I assume there's something fishy going on. This time my instinct is that it's a long-time player who lost her main account.

Would you agree or would you avoid the trade?
