re: Hacked/Compromised?? Thoughts/Suggestions Needed.

Most local police do not deal with credit card fraud because it's a low priority and they don't have the resources. Look up the contact info for the Federal Trade Commission, they have a number (and maybe email) for you to report it.

As others said, you have to assume this was not a one time thing and the person may have just sent a "test order". Request new credit card. Reset any password that has the same login credentials as your WalMart account. Password Manager would be ideal, but for now you should make sure you reset the passwords for any financial institutions ASAP until you can figure out how you want to address a massive change.

Also, if you don't already work with a monitoring company, look into signing up for a credit report monitoring company. Even if it's a free one like credit karma; it'll be something to help watch for activity. CK will catch it after the fact, but you can end it quick; others can catch it before anything happens.
