ASP Query To Access DB & Remove Dups

I have a field called store, I have more than 1 row with the same store name in the store field.

I need to coolect all the stores from the store field, remove any duplicates, like I might have buy.com twice and only need it to show once in the drop down. And sort ascending (by store name).

Summary.
Database is called: tracker
The table (and the only table) is called merchants
I only want to pull data from the field store, remove duplicate store names, sort ascending.

I can figure out how to plug the required htm around the asp code, to auto populate the drop down.
