The point then is to not have a blacklist of eBay sellers that anyone can libel/slander/whine about in a public forum, but for Forum members to remain aware and educated of alternative sources to eBay for clothes so that they can always get the best price available. A blacklist reeks of McCarthyism. Who gets to decide who is on or off the blacklist? What gives them that power and authority? Besides, if a seller is a troublemaker or providing unsatisfactory service to his or her customers, his or her eBay feedback will reflect that. If you don't like what you see a seller doing, then you have the freedom to choose to not bid and walk away. If you want to make other Forum members aware that arbitrage is taking place in the market, fine. Just say "Hey, some ebay sellers are buying stuff on BlueFly and Yoox and reselling it on eBay. You might get better prices on BlueFly and Yoox. Go there first before shopping on eBay." But singling out sellers or arbitrageurs and suggesting that they be blacklisted for their entrepreneurial savvy is NOT fine. In fact, it's a little Orwellian. Yes, you are competing with these eBay sellers for the clothes on Yoox or Bluefly. You are also competing with these eBay sellers for the discounted clothes at Neiman-Marcus Last Call, Off-5th Avenue, etc. It's no different whether or not the items are just one short URL away. A blacklist is not the answer -- competing better is. Get there first. Beat the resellers to the bargains. If competing that way is not that important to you, then just wait for the resellers to buy up the clothes, put them on eBay, and pay a slightly higher price. But don't pay exorbitant prices. Be smart. Know the value of the item. Compare that to the asking price. Bid or don't bid accordingly. In a way, the resellers are actually providing a valuable service when it comes to deals at Last Call and Off-5th -- they are finding and "harvesting" deals restricted to one geographical area -- like Dallas for example -- and then making these deals available to you and the rest of the world via eBay. If it wasn't for the reseller, you would not have ever been aware of the existence of the highly-discounted item in Dallas. You would have had to travel to Dallas or hire a personal shopper to find it yourself. The fact that the item is highly-discounted on eBay and available for you to buy is a value-add that the reseller provides. He or she should be reasonably compensated for his or her time and effort. What is reasonable compensation? Social engineers and egalitarians would try to decide on and put a compensation scheme in place that would reflect what THEY think is "fair". Thankfully, in America at least, we don't live in such an egalitarian society where the "educated" few decide what is best for the masses. Instead, the masses have the freedom to think for themselves and decide what is best for them themselves. They are the market and they decide among themselves what is reasonable compensation on each and every single item put up for sale on eBay. Sometimes, the seller is compensated handsomely. Sometimes, when an item just won't sell at any price, the seller loses all of his or her money and has to give the item away to Goodwill or The Salvation Army. That's the risk the seller takes when he or she trades cash for inventory HOPING to trade that inventory for even more cash. That is "fair".
