So, I'm sure if you're at all interested in RPGs in the 21st century, you've heard of DriveThruRPG*. It's basically the Amazon of digital gaming, both in its retail dominance, self-publishing empowerment, and affiliate program, in which participants can get a small percentage of the price of any purchase made through a particular link, for example the one above. This percentage does not increase the price of a purchase, rather it comes out of DTRPG's take.
I've been using DTRPG affiliate links for some time now, usually marking them with an asterisk that leads to a footnote summarizing the above for transparency purposes. Instead of that, I've decided to make a page with that information.
And now for a demonstration: earlier this week, Lamentations of the Flame Princess* announced a sale reducing all their PDFs sold through DTRPG for just $2.00 each, or $1.50 each for their LotFP Everything Bundle* (this works out to about $82.50). This includes the full (NSFW) art version of the core rules*, Ken Hite's excellent Vietnam-War-inspired setting Qelong*, award winners like A Red and Pleasant Land* and Broodmother Skyfortress*, basically every weird, fantastic, and downright horrific book the company has ever produced - right up to their most recent Gen-Con releases*. Believe me, $2.00 is practically a steal for some of these, but the sale only lasts until the end of the month. Once it's October in Finland, it's back to full price.
