Pac Man's 30th Anniversary (and a Sale)

I suppose I'm late to the party with this, but Namco is having a sale on Pac Man through May 24 in the Android Market to celebrate Pac Man's 30th Anniversary. Reduced from $6.99 to $3.99 I still think it's expensive given how many time's I've purchased the game for different platforms... especially when iPhone owners get Pac Man Championship Edition (among others) for a mere $.99.
