Let me say, from the outset, that I've never sold on Discogs. Thus, I have no familiarity with that aspect of it. What I can say is that I've had a satisfactory, nay wonderful experience in filling in gaps in both my collection of LP's, 78's, and Edison Diamond Discs. Some of the LP's are those that were on a "want list" as far back as middle school, and I've been able to purchase them at reasonable prices, in some case unopened. Grading seems to bring out the whiners as to those who want everything absolutely perfect. Maybe these children should collect 78's or Diamond Discs. There's no such thing as Mint, and you have to live with that. I've found grading to be accurate. As to communication with sellers, those who were somewhat dilatory simply received a polite message inquiring as to the status of the order and Presto! They mailed the package.I've found Discogs to be a helpful means of acquiring music, same as eBay.
