I recently had my first experience as a buyer on Discogs. Unfortunate to say it wasn't a pleasant one.
Long story short, a seller cashed the money and did not ship the order. Delays, excuses, more delays (weeks), more excuses and very poor communication. Ended up cancelling the order altogether and resorting to a credit card charge dispute. Perhaps not directly Discogs's fault but certainly a tremendous lack of control and enforcement of their 'Sales & Transaction Policy'
Unfortunately, bad news spread faster than good news and -lesson learned- I will no longer be purchasing on this site.
What baffles me most is that that particular seller had very positive reviews (over 95%)
This lack of oversight is a killer to the Discogs platform since I am sure there are reputable and honest sellers willing to do good business.
Lesson learned. Buy local.
