Anyone else seeing a massive influx of NPB's lately? I have setup strict rules for who can and can't bid on my items, the strictest possible at this point. most times I can spot an NPB during the auction before it ends, and 90% of the time if it ends, I can predict who will and won't pay. most people want to pay asap for what they buy, to get it quicker. I even ship priority mail 2 day shipping for those people who pay instantly. I have only been wrong once in the last 90 days when it came to predicting an NPB, and that still involved opening a case to get the buyer to pay, 300+ feedback account oddly enough, and he paid on the last day possible before the case closed. I currently see anywhere from 30-50% of my auctions being hit with NPBs... any thoughts on this? I do suspect occasionally that its other sellers with junk accounts, bidding up my items to deter other buyers to their auctions instead.. I mostly sell power tools, and occasionally new and used electronics, but power tools have been my staple last few months.
