NAYRT, but this behavior is so scummy, and sadly way more common than it should be. People should always be wary of "cold calls" for that exact reason - you don't want to overpay for what they're trying to sell you, or get underpaid for what they're trying to buy. That's why I always include recent, verifiable price history with my sales inquiry PMs. Something like, "hey there, I was searching for ___ and came across your dragon, (name) #___ - would you possibly be willing to sell? Here's a list of recent forum auctions (successfully sold or not) so you can get an idea of the current market. Here are the qualities that impact your dragon's pricing. Given that information, here is the price range I am prepared to offer. Here is the reason why I am interested in this dragon specifically. If you aren't interested in selling, feel free to ignore this message, and thank you for your time."

Some people have difficulty saying no, so writing your PM with a built-in "acceptance of rejection" is a great way to create more comfort in the interaction for the person you are approaching. Using this approach has lead to a sale around 80% of the time for me, and I have never actually been ignored thus far.
If your PM is rude or off-putting, that doesn't create the environment of cooperation necessary for a successful transaction. Politeness is key!

Those who take advantage of kindness or naivete might get a hold of what they think they want materially, but with such a skewed approach they will never be able to keep hold of true happiness.
