This is definitely not the case for me with 99% of my dealings with folks on the CABE, but recently I sold an ND two speed rear end with shifters, etc. to another CABER from the 'for sale' section. I put a very nice price on it, well under what I probably could have gotten on ebay for it. I posted lots of large clear photos of it as well, and even told the buyer to please ask for more photos and be sure he knew what he was getting and that he wanted it. I don't know that much about these ND 2 speed set ups, in fact had just posted questions about IDing what I had, so I expected buyers to look at the pix and decide if it's right for them.
Well, the buyer received the thing quickly and well packed, and I sent a tracking number immediately. It was exactly as described and photographed, but the buyer decided to say I misrepresented it and wanted me to adjust the price. I told him to just return it, but the only response I got from him said he would always remember me as a "dishonest seller". Again, I replied to "send it back", but never got a response after that. His only goal was to further negotiate the already good price, and grind me down further.
Soon after, I noticed an ebay seller (coincidentally with the very same name as the CABE handle of this buyer) selling just the shifter, and it closed for more than half the price of all the stuff I sold him. I looked at his past sales, and clearly he has been trying to get parts from CABERs at the lowest possible prices, then sell on ebay to make his profit. It's his right, of course to buy low and sell high, but this kind of grinding tactic with a private seller is really abhorrent to me when it's really just to make more money. The end result is I will think twice before listing something here for a good price instead of just going straight to ebay with it. It only takes one bad, money grubbing actor to ruin the goodwill of sellers here on the CABE. The bike community as a whole is quite wonderful, and I've had many, many good exchanges with folks here. I've forged some excellent friendships along the way, but sadly there are people like this exploiting the goodwill and good nature of sellers here for their own personal gain. I will not name this buyer, but if you want to avoid the same fate with him, PM me and I'll fill you in. Now that I know his game, I will certainly avoid him altogether in the future.
