I know what a lot of you mean. I had that same sort of LGM fustration, last week.
If I was not making money or if customers didn't want I wouldn't sell it, I win some auctions I loose others. All my prices are market driven, how many people you see list stuff at a penny? People pay what they want.
Side story, I bought a blues brothers poster a couple of years ago. i thought it was an original/ didn't matter to me if it was. I paid almost 270 bucks for a 10 reprint. Some dude was mifffed that spent the same amount. He wanted to file a complaint. I said I would have paid 500+ I wanted this poster for so long never have seen it again. I knew what I wanted and got it. People pay what they want. I didn't ask the guy back for 250 bucks, since it cost him all of 2 bucks to make...
Its like people want to comment when they don't have anything to say but still say something, thats the fustration.
I offer deals, I offer refunds, I call it as I see it, in my world. I have made some mistakes and learned from them. I know what I sell and I do a pretty good job at it.
