Charlie, we get fewer than one in 4,000 items returned for missed defects or over-grading, so I KNOW our system works.
Actually, as you point out, ALL grading systems work when the sellers are honest in their grade and point out defects you can't see in their images.
I think is it not just the items that are returned but items buyers think about returning too. For example, I can recall only one item I thought of returning from your auctions Bruce, but when I went back to the description you had clearly stated the defect. It was my oversight so how can I blame you.
And No I am not Mel's secret double agent for Bruce... I would further say I've never thought about returning anything from Hideyuki, Dale, John Reid, or than cinemacollectorsvegas guy - Or Vesna and others over PM deals...
In regards to two particular dealers Dave (Cinemasterpieces) and Heritage I've gotten items delivered that to me were questionable especially since all I relied on was their grade and photos. My first ever purchase from Dave had a piece of tape which I could easily remove as well as pin holes; if I recall neither were written down in the listing. As for Heritage there was an ugly stain on my Cleopatra Insert that was not described in the write up just a broad shotgun approach for the grade. The image did show a boosted stain which was much more noticeable in person so I did not return - my mistake but I don't take full credit. And then the whole Terminator quad debacle. None of these I returned but they were both "check marks" in the negative columns. I have not bought from either again. Although I do think I would buy from Dave again - just nothing of interest lately.
I guess if I were to provide some advice for anyone's endeavor to sell posters: is to not to solely rely on the number grading system or qualitative wording system but make sure to describe defects in
detail. There is nothing worse, to harm a reputation of a seller or selling system, than disappointment. Every buyer wants to be "wowed" when he opens that package not "Oh crap I didn't see that stain or pin hole. Now I have a POS and no money to buy another." Yeah, yeah, you can stand behind your return policy but why should I have to spend my time making up for your incompetence in describing a product accurately. And I am not just singling folks out, I think every seller could do a better job even if they are doing great now. I think the biggest fear of some is that if they describe a poster accurately it won't bring as high of a price that it would under a 'vale of vagueness'.
I think I experienced this first hand when I recently ran some auctions and described every major issue with the posters and didn't get a single bid. But perhaps if I would have gone with 8.5 to 9 based on the MPE model, I would have sold many of them. No collector likes to read "Scratch", "Stain in corner", "Dog Ear", "Fold Separation"... But worse is seeing something for the first time when you open the package.
No one wants to feel 'had' or 'stupid' and that is what can happen when a dealer leaves the buyer to do his work. Working under an attitude of 'Buyer Beware' is not always the best way to gain and retain customers. This is especially true if buying from so called reputable dealers because the expectation is there. Commitment to trusting a dealer and, even once, getting the feeling of being had or left to fend for yourself is a black mark. Dealer's who do this are not better than the hacks on eBay IMO.
And then to the complaint of not having time to study each poster for defects... It takes no more than 30 second to look over a poster in detail and another 90 seconds to write it out. Success has two routes: through hard work and through cutting corners and lies. The latter may have great successes in brief flashes but often a great failure. Dealer's don't be afraid of hard work and honesty - it will pay off.
OK enough of my soap box BS...
