This has been a very, very common thread topic in the Pin Discussion area since DPF started. Yeah, these guys are out there and they suck, a lot. I remember a thread years ago where we all just up and confessed to having bought a pin lot like that when we started. It happens to probably 50-60% of pin traders because it is an expensive hobby. I fell victim to it myself a long time ago, when Jessica and I were first starting. We were ecstatic to get 50 pins for 70 bucks, what naive trader wouldn't be? We saw the prices on the racks and thought we had found the deal of a lifetime until we tried to trade other traders in the park and got thoroughly embarrassed.
Rule #1, if it sounds too good to be true, (almost) invariably it is. It was bad enough where US customs stepped in a couple years ago (I think) and caught a shipment of fakes worth $2,000,000 coming in from China (there is an old, old thread about it if you can find it). Made a small dent, but it keeps happening.
The thing that pisses me off the most is that these guys have 100% feedback. Probably 70-80% of that comes from parents looking for a cheap activity for their kids while on their Once-Every-10-Years Disney vacation. 20-29% of that feedback comes from traders that are either 1. new 2. don't know any better 3. don't care or 4. a combination of some or all of the above. A problem arises when a buyer receives a shipment of these abominations and figures out they got duped. If they confront the seller as you did, the seller, while pissed off, does EVERYTHING THEY HAVE TO to make you happy for the sake of positive feedback. The worst part is, they usually get it.
I think the absolute best thing a buyer could ever do that figures out they got duped into buying fakes is LEAVE NEGATIVE FEEDBACK no matter what the outcome. Even if you receive a 100% refund, leave negative feedback that says in big, all caps letters "THIS GUY SOLD ME FAKE PINS!!!!!!" Enough of these show up and at least that account will have to close. I think I even remember a renegade group of DPFs way back in the day that banded together and did this till they drove someone out of business, so it works. And remember, an eBay seller CANNOT LEAVE A BUYER NEGATIVE FEEDBACK as long as the buyer has paid for the item in a timely manner; they can just try to leave a pathetic note attached to your feedback you left them.
I think too that if you open a case with eBay and notify eBay that you received counterfeit merchandise there may be a way that you do not have to return the item to the seller; I wouldn't want to give a counterfeiter back his bad stuff just to have it passed on to someone else.
Blingy, please, please, please leave this guy bad feedback. Just think, you might save another person, just like you, somewhere down the road from having to go through the same process.
