confused about Mr. Hook's website info

[Guest guest]

>>>>>>>>>>>Three Cal-Mag-D capsules are taken three times daily after each

meal. 

Servings Per Container: 30>>>>>>>>

just saw the above on Mr. Hooks website, just copied it here verbatim....but

wondered does this mean that if you have to take 9 of Mr. Hook's " cal-Mag-D "

capsules every day, you go through a bottle of 30 every 3 and a half days?

That seems like that would be really expensive?

Just wondering
