This starts now, more or less. The game is Deadlands, the Old West with magic etc., which I've tried a couple of times and quite liked, this offer seems a good way to get into it cheaply:

"This brings back a very popular offer featuring the original 1996 Weird West tabletop roleplaying game from Pinnacle Entertainment designed by Shane Lacy Hensley. This revival runs until Tuesday, August 11.

All of these are PDFs without DRM copy protection. This may not seem like such a spectacular discount as the last Bundle of Holding offer, that's because the retail prices were already reduced considerably from their original publication.

The way that this works is that the sooner you buy this, the cheaper the bonus collection.

Ten percent of each purchase (after gateway fees) goes to this offer's designated charity, the National Center for Missing &
Exploited Children: http://www.missingkids.com/WhatWeDo

Usual caveat - The main reason I know about this offer is because I'm on the list to get this stuff free if I want it. In this case I do, but whether I do or not, if I think these are bad deals I'll say so.
