I just did some quick maths on the current sale (a first for Shrapnel?).
WinSPWW2 (Free or $40 for some extra resolution, encyclopaedia options and other minor features) has been reduced in price by $5.00 (13%). That is about the same percentage that inflation has reduced it's price by since it's release in 2006 (13.3% CPI).
Even in 2013, 35$ is too much for my pocket. I'm going to sit it out for a good many more years and hope Shrapnel don't increase the price with inflation!
