Amazon.com responded to my complaint about the inappropriate promotional email (see yesterday’s post). They get credit for responding, especially since it looks like a human being actually was involved here. Gopi N’s response was pretty much boilerplate, and didn’t respond to my request that an apology email be sent to those who received the first mailing.
Here, for your information, is the bulk of the note I received from Amazon.com:

Thanks for writing to Amazon.com to bring this to our attention.
We build our web site information from many sources, and we really appreciate knowing about any errors which find their way into it.
I’ll see that this error is corrected as soon as possible.

[MDR: I’m impressed that these last two paragraphs seem to accept that there was an error made. Usually letters like these allow only that somebody perceived errors to have been made.]

For future reference, at the bottom of the product detail page of every item on our web site, you should see a blue Feedback or Suggestion Box where you can report any inaccuracies in that item’s listing on our site.
Thanks again for shopping at Amazon.com.
Please note: this e-mail was sent from an address that cannot accept incoming e-mail.
To contact us about an unrelated issue, please visit the Help section of our web site.
Best regards,
Gopi N.
Amazon.com Customer Service

It will be interesting to see if Amazon.com does anything else with this complaint. I’m not crossing my fingers.
