C++11 standard document costs

问题:

Why are there different PDF versions of the ISO/IEC 14882:2011 standard (C++11), which cost from $30 to $761? (see http://webstore.ansi.org or any other distributor)

btw.: Has the INCITS $30 version just been published? It's available at the ANSI web store, but not at the INCITS web store..

It's just the way the standards organizations work. They're not competing with each other to get your business.

You can basically get the C++11 standard for free anyway. See n3337 here. It's the standard plus the first few post-standardization corrections of typos and the like.
