Those are different categories, so adding one should not be treated as adding the others. Inspect the offer available for your pet and state instead of combining every benefit described somewhere on the website.
For preventive care, compare the additional premium with the allowances for services your pet will actually receive. A maximum that includes unused services is not the same as an expected reimbursement. Also check timing, frequency and eligibility restrictions before counting a benefit.
Suppose a fictional routine package costs $180 for a term. The owner’s planned eligible services would use only $125 of its separate allowances. Without other valued benefits, the package adds $55 to that planned spending rather than saving money. These are invented planning amounts, not a quote, reimbursement forecast or recommendation to skip care.
