Used discogs for multiple years and never had any issues. Yes there are some scams but as long as you look at reviews from the seller (awesome feature user-based stores usually dont have) before you buy to make sure they are legit then you will be okay. Its the same as amazon. They obviously can't moderate every single listing as there are hundreds of thousands of them so it is up to you to make sure that what you are buying is safe and legitimate. And since your money usually goes straight to the seller and not through discogs, discogs themselves can't get you a refund. It is not a normal online store, and people need to stop acting like it is. Great buying experience as long as you aren't stupid.
