What is Reddit's opinion of Nevermind [4 LP Deluxe Edition]?
From 3.5 billion Reddit comments

By popularity on Reddit, this product is:

2009 blue ltd/4000 LP sells for an average of $116. https://www.discogs.com/sell/release/2015683?ev=rb

10 inch box sells for an average of $65. There are 50 copies on discogs right now, most for around that price. https://www.discogs.com/Nirvana-Nevermind-The-Singles/release/3247502

Simply vinyl 180 gram sells for an average of $51. There are currently plenty of discogs available for that price. https://www.discogs.com/Nirvana-Nevermind/release/504129

So this collection is worth MAYBE $250, not even close to $700. None of this is very rare and certainly none of it is PRICELESS IN ALL CAPS.

The "regular" 20th Anniversary Edition (on black vinyl) is also available for preorder.
