I would much rather sell here than ebay but some things just sell better on the bay. This place always gets my precedence. That said, in my sales I clearly say I will sell (or not) to whom ever I want. A knife is never sold until I have the money. Way too many flakes, low ballers, noobs who have no idea what they are doing to hold a knife based on an "I'll take it". Hell, just today I had a guy ask me to email him about a knife I have listed here. He asked 8 other people to email him about knives also today. Last month he asked for a trade on the same knife even though I said no trades. I wouldn't take his money even if he paid double. Not worth the headache. Same with some nut on the bay. Idiot hit the buy it now option and then proceed to email me a low ball offer. I said no, filled a claim, blocked the buyer, and relisted the item. Doesn't matter if he/she would have agreed to pay my asking price after all. No way I'm am sending my knife to a low balling flake.
Point is, the knife isn't sold until it is paid for. Too many flakes to do it otherwise. That said, if you send me your money the knife is yours. I don't give out my paypal address to multiple people at the same time. If I give you the paypal here and I have the knife on the bay also the listing gets pulled. Someone who accepts payments for the same item from multiple sources and does it repeatedly does not belong here.
