Yep, there's a D&D 5e sale going on as RPGNow as I type this and it lasts for the next 9 days or so.
Now, to be honest, the depth of my 5e product knowledge is pretty shallow compared to the OSR but there are some things that deserve highlighting.
Depths of Felk Mor - an old school styled megadungeon for you 5e game that will take your party from levels 1 to 10. I have the soft cover next to me for review purposes (I need to read the whole thing - like what I see thus far) and it has a nice heft to it ;)
What follows are repackaged Encounters storylines...
Ghosts of Dragonspear Castle - this was written for (and includes) the last of the 5e / D&D Next playtest rules. Includes all you need to get your characters to level 10. Nearly 300 pages.
Dreams of the Red Wizards: Scourge of the Sword Coast - continuing the storyline from Ghost of Dragonspear Castle.
Dreams of the Red Wizards: Dead in Thay - continuing the story from Scourge of the Sword Coast.
Murder in Baldur's Gate - comes without 5e / Next, 3.5 and 4e stats. Yes, editionless.
Legacy of the Crystal Shard - again, without monster stats, so edition is flexible.
Strangely enough, the current Adventurer League releases are not included in the sale, unless you grab the bundles, which come in at 40% off.
