For the people who do the feedback, it becomes really obvious who the repeat offenders are and they are typically the ones who get branded.
I think nothing is set in stone until money has parted hands. It is annoying and not exactly good etiquette, but I don't think its wrong per se.
So is it just me, or would you guys think it wrong to have a deal ready to go then the seller back out because they got a "better" offer? Happened to me lately and, I dunno, just REALLY annoyed about that.
I can only speak for me, but I find I am far more forgiving as a potential buyer than as the potential seller.
As a potential buyer, if the person pulls the rug out under me, I've lost a few PM or emails maybe, it's not great and it's not great etiquette, but at least you've really traded for something after all. ( I.E. you've "Traded" for the knowledge to avoid that person for there to the rest of eternity. When deals go bad, red flags were always there from the start that the person would pooch you. )
As a potentially seller, it's a whole different ballgame, I may lose out on other offers, take the time to take photos, pull something out of storage, spot check for minor defects or box wear, get a shipping quote for international people, etc. As a seller, it could be costing me more than a few PMs to someone who just bails out.
The guy you slight today might be the last guy who has Item X at a killer price in 5 months down the road who won't even look at your emails anymore.
I think folks have to try to take a step back and see it all across the board in wider view. If 98 percent of your deals here are good and you are typically dealing with really solid people, then I think you almost have to write off the 2 percent of scrotum cheese as the cost of doing business. I've gotten really nice deals here at nice prices and met some pretty cool people. 98 percent of the time I am dealing with fellow hobbyists who love toys/collectibles and in this kind of hobby, trading with someone is almost like having a long distance meal with them, there are gestures of goodwill involved even though it's basically commerce. The 2 percent just remind me to appreciate the 98 percent more. Generally speaking, the 2 percent will eventually watch their trading options dwindle over time ( unless they consistently sell for a massive loss), just won't happen in the time we might want.
In the end, people can't sit at that table jerking around the waitress and people around them forever, eventually the tab comes due. Decent folks are better off knowing there are better tables with better company to eat with.
