I have been a Seller and a Buyer on eBay. In disgust, I gave up my membership. EBay has become a Buyers dream, as there continues to be many thousands of Sellers who allow eBay to charge them disproportionately high fees, then to disrespect them by never backing them up against unjustifiable complaints. To put is simply, all that a "Buyer" needs to do to vent their frustration is to enter a "Negative" against a Seller. To get the "Negative" removed the Seller must refund all of the "Buyers" costs, not expect to have the item returned, then the "Seller" must beg the "Buyer" to voluntarily remove the "Negative". This happened to me twice in about 750 "Positives".
As always, I had done as I promised, but the first "Buyer" simply gave feedback stating "This isn't what I had expected" then gave a Negative... not once did he write me as eBay says they should, and eBay totally backed the ignorant Buyer, not helping me whatsoever. "The last time a Buyer gave me a Negative, he stated that a banknote which he won "looked like a copy"; however it was crisp uncirculated and genuine. Again, no writing to me, which would have resulted in a refund, as it's much easier to refund than to try to argue with a fool. But eBay would not intercede, nor back me up. Instead it assured me that I could not give either "Buyer" a Negative, or to state that they had not even once attempted to contact me, as a Seller being able to tell the truth or to defend themselves is against eBay's policy!... I cancelled my eBay auctions and told them that once they apologized to me, changed the rules to protect their honest & decent Sellers, and refunded me my losses, that I would again sell on their website. Instead, they've continued to bill me for the auctions which I cancelled.
EBay is run by folks who have figured how to maximize their profitability, and to do the least work to maintain. They have created so many rules to protect themselves, and to ignore their own Sellers. Their seemingly honest efforts of working with the Sellers, always result with referring the Seller to this or that rule and regulation, and requiring documentation upon documentation, then going their happy way knowing that for every defense that the Seller may offer, that there was a rule with which they would find impossible to comply!
For example, for a Seller to send an item to the "Buyer" who is determined to rip them off, a Seller must send the goods with Insurance, and Signature Required... only to have the "Buyer" state that the package was empty or had rocks, etc." in it instead. There's no way to defend yourself against an unscrupulous "Buyer", and eBay won't even allow a Seller to enter Negative Feedback against any "Buyer"! ((With this rule, eBay avoids a lot of "Unnecessary Work"!))
Although it may seem counter-productive, because they are still the major on-line auction, many Sellers simply pray that they don't become prey to the bad Buyers.
I will not sell on eBay again until they acquiesce to my demands of fairness, apologize to me, and refund me. However, that day is not in the foreseeable future.
