Ok, here's my $.02....
I don't find anything wrong with buying on eBay to resell. I've done it and a lot of other members here do it as well, and it's a nice way to make some extra cash.
I think what got people upset was when the BIN was posted here, and another member expressed their interest & was waiting on a response from the seller before using the BIN.
Yes, I know that BIN's are first come first serve, but you jumped in and bought them just to make a profit. Of course there's nothing technically wrong with that, but I feel like most members here try to help each other out with getting good deals, staying away from fakes, etc.
I don't think this should turn into a major deal (because after all, we're talking about jeans here, not saving lives
) but I hope this helps you understand why people got upset.
And I have to say, when I saw the title of this thread, I thought it was going to be a question about a 2nd chance offer on eBay. Ebay has taken over my mind!
