Traditionally speaking my buying of trade paperbacks has followed a simple rule:
Forbidden Planet = Bloody Expensive, Amazon = Good Value
However, this doesn't seem to apply for Forbidden Planet's online catalogue, where the prices seem to frequently undercut Amazon and they get things sooner - sometimes months sooner.
Take, for example the new Absolute Death hardcover. Amazon have it for £52.50 - FP Online have it for £50.25 (plus £1 shipping). So £1 cheaper at FP - big deal. Except that Amazon have it showing as in stock from the 18th of December, and Forbidden Planet delivered it to my door an hour and a half ago (huzzah for Julie being in slaving over her stats).
I assume that Direct Market comics just run ahead of book stores - which you wouldn't think Amazon would be happy about. I wonder how long that will last.
