yes, I never buy anything below mint or near mint, I never relax that rule, and i read a lot of the feedback. in about 100 transactions , two were clearly fraudulent and i took them to task in the feedback and thru discogs help.
one idiot who runs an antique shop in Sedona sent me a trashed album. I told him it was two or three grades below how he rated it and filthy and I asked for a refund of the difference in value and that he donate that refund to a local food bank...he tried to whack me with negative feedback, he lost that war...
