This reddit list is the absolute best place to visit to find these bargains, it includes all the links direct to the deals. The main post is providers, and top comment is indexers.
Great list because it's sorted by backbone - grab an unlimited account from one backbone, and a backup block account from a different one!
My favourites bargains are:
-$20 Lifetime NZB Geek ~expired~
-$5 althub unlimited yearly
-$30 Newsgroup Ninja unlimited (updated to $30 as pointed out by user VIVh)
-$5 500gb block usenetexpress
-$10 1TB block newsdemon
-$40 thundernews unlimited
Hopefully this is alright to post here otherwise this ozb will be absolutely spammed with fairly niche deals.
~PRICES IN USD~
