Discogs Better Price Sorter от Mongolian Miller

Due to the terrible design of discogs.com, if a particular album has hundreds of listings, I recommend increasing the "show" number to as high as you can so that when you sort the pricing, you get as many sorted results as possible.

Due to pagination, this wont sort beyond what is loaded on the page -- so you may have to go to page 2 and sort those as well, etc.
