It's all about selling tactics. Some people like to put higher price and then expect buyer to bargain and then settle for reasonable price. Some people just offer a straight up price and stick to it.

Unfortunately, those who start with high price is definitely open to comments of their price being ridiculous and all. It is all understandable. You should expect such comment when you post higher price. IF you can't stand those "comments" then just put lower price. If you want to put high price then you just have to take those comments.

I personally think people who put high price is just people trying their luck to find some noob who doesn't know about prices. In chinese term, WATERFISH.

I personally never like this method of business. I have been member since long time ago...look at my Joined Date. I have sold like more than 50 items since joining and I have never once had people commenting my price high in a nasty manner. Maybe once or twice just subtle comment. I just don't simple put crazy high price to sell my secondhand items. I feel that is how business in FORUM should be. If you want to do business like high price, bargain and all then better go to ebay or lelong.
