Unrelated, but this reminded me of this old chestnut that still makes me smile. It is from comp.lang.c FAQ, e.g. <https://www.cs.rpi.edu/courses/fall96/netprog/cfaq.html>:

        The cost is $130.00 from ANSI or $162.50 from Global.  Copies of
 the original X3.159 (including the Rationale) are still
 available at $205.00 from ANSI or $200.50 from Global.  Note
 that ANSI derives revenues to support its operations from the
 sale of printed standards, so electronic copies are _not_
 available.

 The mistitled _Annotated ANSI C Standard_, with annotations by
 Herbert Schildt, contains all but a few pages of ISO 9899; it is
 published by Osborne/McGraw-Hill, ISBN 0-07-881952-0, and sells
 in the U.S. for approximately $40.  (It has been suggested that
 the price differential between this work and the official
 standard reflects the value of the annotations.)
