Drivethrurpg is having an "OSR extravaganza". 1302 Items are listed on the sale page. Of interest to me is the list of game systems: Apocalypse World Engine, BRP (Basic Roleplaying), Dungeons & Dragons, Fate, Old-School Revival (OSR), Pathfinder-OGL, Savage Worlds, Storyteller / Storytelling, Traveller. Only a few of these I would consider OSR (Like OSR, BRP and maybe some Dungeons and Dragons). The OSR is broken into some more sub catagories: Castles & Crusades, Dungeon Crawl Classics, Labyrinth Lord, OSRIC, Swords & Wizardry. Limiting the items to just OSR cuts the count to 816 items. Selecting core rule books drops the count to 48 items most of which I own (however "Apes Victorious" keeps tempting me even though I hate "Planet of the Apes"). Selecting Adventures yields 368 items (I may pick up "Hubris" even though post apocalypse is not really my style). Although the main sale is not that much of a discount (only 15%) several bundles at deep discounts have been offered. Annoyingly the bundles are not listed on the main "OSR extravaganza" page. However a search for bundles turned up the following:

Fortunately for me I own the original books offered in the AD&D megabundle and most of the Planescape as well so I didn't go for those bundles. I only have four of the known world gazetteers and this bundle is priced at the cost of one hard copy of a less popular one if you could find it, so I was happy to pick it up. The Rules Cyclopedia included in it is one of the better written versions of D&D so picking up the .pdf may help, although I already have the hardback book (still can't get onboard with race as class though). I also bought the OSR(IC) Extravaganza as I have found most of the Advanced Adventures I have purchased well done and the only one I own in this bundle is the "Frozen Wave of Satsuma".
This next bundle also showed up with a deep discount in my search. However it appears to be for memorial day rather than the "OSR extravaganza" so if you are interested act fast. I do not know much about this publisher.
