STARTER COLLECTION (US$8.95 - retail value $41)

• On Her Majesty's Arcane Service (Better Mousetrap Games, $10)

The way that this works is that the sooner you buy this, the cheaper the bonus collection. They're DRM-free PDFs. There are also going to be extra bonus items added as the offer progresses, anyone who pays the bonus rate will get them.

Ten percent of each purchase (after gateway fees) goes to this offer's designated charity, Reading is Fundamental.

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 even if I didn't it seems like a reasonable offer. If I think these are bad deals I'll say so.
