The building with the Christmas tree on its corner is located in Pittsburgh, PA. Formerly Horne's Department Store, it is now an office building.
Jon Prescott (Tom) is an accomplished musician and singer. It was really him playing the piano and singing in the store after closing.
The only time the store name "Wolman's" appears is within the inappropriate Beefcake Santa video.
The movie shown on the television in the apartment is from another Lifetime movie, Holiday High School Reunion, which had Jon Prescott (Tom) and Josh Crotty (Bruno) as cast members.
