These are nationwide and include mail order. Just remember to search you need to only type a few character of any of the criteria fields. For example, Wal-Mart is just like that, with a dash, so trying 'wal' is best for the pharmacy name and then including a city or zipcode if its a local pharmacy.
If you are searching for a mail order pharmacy, it is best to click on "Clear" first, so your default State is not selected. Many mail order pharmacies are in different states.
