Buyer has ZERO feedback. Buyer send a $500 offer on a item listed for only $150 on eBay. When contacted about this, since it could be a mistyping mistake, buyer never respond. No other choices than declining the suspicious overpriced "best offer" and block this buyer on eBay. I suspect that if I went through with it and accepted the best offer, buyer will have probably open a NAD case on eBay as soon as he receive the item to get his money + shipping back.
