Thanks Tony S. I guess my post does make it look like I'm trying to prevent any returns at all. That's my fault for not being clear in my original post. I have much more experience selling vintage toys on ebay and in that market once you take good pictures, list any flaws and describe the item in good faith, returns are practically nonexistent unless there is damage during shipping. That makes me feel like I have control over the rate of satisfaction with my listings. I guess I was spooked by the posts about how it doesn't matter how accurately you grade a comic book, the buyer only has to say they disagree and ebay sides with them. Also the posts that describe how ebay does nothing to stop switches during comic book returns. I never heard of that happening until I started to look at the comic book market. That makes it seem like the comic book market offers less control over the satisfaction rate unless you deliberately undergrade. Perhaps I'm getting a skewed impression of the market. I have a 100% positive feedback rating after over 1,700 transactions and my reputation is more important to me than any single transaction so cheating people is furthest from my mind. Anyway, I'm reading more on this site and have come to the conclusion that my only choice is to learn how to grade conservatively, how to spot restoration and expect some returns as business as usual. Thanks for the replies.
