Using the table

Start with the three-year total, then see what each price includes. Planning to add a state later? Count coverage heavily.

Reading the order

Three-year total and what a price buys carry the most weight; year-two change, break-even and detail follow. A reader could live anywhere, and for that reader a single price in all states outweighs a lower price in one. Owners in New Hampshire or North Carolina can save with NH Registered Agent.org or North Carolina Registered Agent.co.
