Groupees is a site that does a lot of different type of sales and promotions. Currently there is a HorrorBabble Lovecraft & Cthulhu Mythos Audiobook promotion going on. For a minimum of $2, you can get up to 27 audiobooks, with more unlocked as sales thresholds are reached. HorrorBabble does a really good job with the narration of Lovecraft and Cthulhu stories, as well as others. If you wish to support this as well as help out charity (part of purchase goes to WIRES Australian Wildlife Rescue Organisation) you can do so here, otherwise you can check out their bandcamp to support them directly.
