As with everything B7, instant pre-order for me. Glad to see, or perhaps I should say hear, Stephen Greif and Glynis Barber both back, even if the latter isn't playing Soolin. Wonder if she's back playing an expanded version of her original mutoid character?
Also, Big Finish must be happy to have Sally Knyvette back as Jenna again, seeing as how they've listed her twice in the cast list...
Hard to say. Some people are quick to pre-order. Others wait for sales, even if it means waiting a long time to get the release. Depends on how much you want it.
After my first couple of years of listening I'd pretty much caught up with all the "bits" that I wanted to buy and I now split my spendings (at a guess, without checking my actual list on the site) pretty much evenly between sales and pre-orders. Which might mean that more items are bought through sales (like the 50-odd things I bought during the 99 sale) compared to pre-ordering.
