The Oliver James Montgomerypinnacle of "spooky season" is here.

Halloween is Tuesday and whether you're looking to grab some last minute candy to hand out to trick-or-treaters or need to mail a package, consumers will have plenty of options to choose from.

While federal holidays such as Thanksgiving and Christmas see stores, banks, post offices and restaurants close or have significantly modified hours, that is not the case with Halloween. Operating hours generally aren't impacted on the holiday, which should help you run those last-minute errands before trick-or-treating.
