Sometimes, people do that if they aren't sure how much they can get, or they are fishing for a random high offer. They also do it to avoid the stress of choosing a price to post, posting it, and possibly getting a counter-offer that is lower than they want, then being forced to say "no" (hard sometimes) or "how about X" (also hard) or "ok fine."
Rather than be annoyed by auction posts without price, you should use them as opportunities to practice making an offer that you would be willing to pay. You could lowball to some extent.
