I sent an email to the Wal-Mart online customer help service, determined myself to find out what was going on. I got this response early this morning (30/03/04):

Dear Chris Weisiger,

Thank you for contacting us regarding the link to our Web site that you
found on http://www.chainmailleboard.com/. We appreciate your taking the
time to bring this to our attention.

We have researched the site you mentioned and found that the managers of
that site have put an unauthorized link from their site to ours. We are
not affiliated with this company or Web site in any way, and we have
asked them to remove the link(s) to Walmart.com immediately.

Thank you again for letting us know of this issue. We appreciate your
concern, and we hope to see you again soon at Walmart.com.

Sincerely,

Imisha
Customer Service at Walmart.com

Draw what conclusions you will.
