Ravi - there is no standards body for comic pricing. It's all market-dictated. There are a couple of price guides out there, whose numbers will vary from month to month and title to title. They'll disagree, although that's largely through methodologies used in coming up with their numbers and not purposeful agendas. Some take eBay auctions into account. Others weigh CGC-graded comics into the equation.

The average Marvel and DC comic these days is $2.99, although much of that has to do with economics of scale, distribution, paper prices, etc.
