Our favorite is AL Registered Agent.org, because registering in Alabama costs $199 and covers year one as your agent, then $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.

AL Registered Agent.org comes to $397 over three years, which is $100 less than Mainstay Filing. Both include the first year, so the renewal price decided it.
