Many of Big Finish's box set and special releases are available for exclusive pre-order prices, which we keep in place from the time they're announced until the sets go on general release. This month Survivors - Series 4 and Doctor Who - The Companion Chronicles: The Second Doctor Volume 1 are on their last few days of great savings...

Released in June, Doctor Who - The Companion Chronicles: The Second Doctor Volume 1 is £20 on CD and £15 on Download until 1st August. This four-story set contains brand new tales for all of the Second Doctor companions, and has been a hit with reviewers (a "must have for fans of the Troughton era" says Sci-Fi Pulse). Any purchase through the Big Finish website comes with some exclusive extras: free download versions of the scripts, and a 24 minute music suite.

Survivors - Series 4 is the latest in our hard-hitting, award-nominated audio continuation of Terry Nation's 1970s BBC TV series, and is proving to be one of the biggest critical successes Big Finish has ever experienced ("10 out of 10" - Starburst Magazine). Until Monday, this fourth set remains available at £25 on CD and £20 on Download.

At the end of the month, Doctor Who - A Life of Crime Part 1 will become free for anyone to download, having enjoyed a month's exclusivity to those who subscribe to the Big Finish newsletter. There'll soon be the chance for a new exclusive preview of an August title too, so sign-up today!
