1) Does anyone know if Best Buy will price-match against Amazon on HD-DVD software?

2) Where does one get empty HD-DVD boxes? I'm planning on getting a couple of the "Best of HD-DVD" 4-disc sets, and I want to put the discs in their own red plastic boxes.

not by policy no. the policy is local competitors for in stock items. Mileage may vary depending on who ou ae talking to at the BB in question.

My Best Buy will NOT price match Amazon, but I have heard of others that will, I think it completely depends on the manager of that particular store.
HD Movie Source sells empty HD DVD movie cases. They are HDMovieSource.com

Sleeve Town (http://www.sleevetown.com/) sells empty hd dvd cases too.

Great prices on HD DVD and Blu Ray replacement cases at http://www.sleevetown.com.

1 for $0.75, 10 for $6.50, or 50 for $28.00.

Best Buy does not price match on-line competitors but I have taken in a Target online printout( they have the same prices as Amazon.com) and have gotten them to honor it.

If it is a new release I generally will go to BB but if it is a catalog title I order on Amazon seeing as how most of the time my Best Buy never has the older movies.

Like people have said it depends on who is working at BB. I did get them to PM Planet Earth at my local BB
