This is a very good question. It depends on what kind of subscription you plan on buying these 3 accounts. If you go with the monthly plan and subscribe all 3 accounts it will cost you $6.95/month per account (so a total of $20.85/month). If you go with the 6-month plan it will be $41.70/6-months per account (or a total of $125.10/ 6-months). And for a year there is no extra discounts so it would be $79.95/year (or $60 if you subscribe during the special rate time) per account.
I do hope this helps! If you ever have any other questions regarding your accounts specifically in regard to billing, don't hesitate to contact support!
