eBay Sellers - Why are Some of Them So Rude?

I'm not an eBay seller, but I am a long time eBay Buyer. Most people would lean towards the eBay buyer as being the more important person. To me, we are both "most important" I have always tried to give the other guy the benefit of the doubt, but , now days, there seems to be more and more sellers out there who conduct their business in such a hostile manner that you don't want to return to their auctions. If you ask a simple question about an item, some reply in such a sarcastic manner that you wind up not wanting their items. Many offer partial or inaccurate descriptions of items being offered, often with very inadequate pictures. Items are often misrepresented as genuine or new or some other misrepresentation. When you ask the "awkward" question, their reply is sharp or nasty! I collect coins and have had several occasions over the past few years when an item didn't arrive at all. Often, emails go unanswered for days and then when they do reply, they lie about when the item was shipped - if it was shipped at all.  Do they not know that there is a postmark with a date on it?  Often, when they have ignored your emails long enough and you finally have to file a claim with PayPal or eBay itself, you wind up going through the third degree just to get the item or a refund. Sometimes you just want to quit bidding. But, thankfully, there are still many good eBay sellers left. The best advice that I can offer is for bidders to read all of the auction details BEFORE BIDDING. If there is a half-page of their "Do's and Dont's", or things like "No Returns Accepted", or "I'm not responsible for uninsured items", don't walk away - RUN LIKE HELL!  Anyone who will not stand behind their products doesn't deserve a bid. The seller has every right to charge a reasonable shipping, handling, and insurance on items sold. And as a buyer, you ARE entitled to receive the product that you have purchased. If the seller has not properly packaged, insured, or shipped the item, that is HIS problem. Legally, the responsibility of getting the product to the customer is the responsibility of the seller.  BIDDING is totally up to the buyer, but unless you plan to buy, don't bid.

This guide is my opinion only. I guess that I just needed to "Vent" a little. Ebay is still the best resource that collectors have ever had. If you feel the same way, I would appreciate your  ( YES )  affirmation below.
