Don't be so fast to dismiss it! The section you are looking for is "Professional Qualifiers"
For example, in Essence Companion, the Demonologist TP states:
Professional Qualifiers: Dark Pact flaw, Open Door flaw, or Dark Temptation flaw [-7 points]
This means that if you have those flaws, the TP cost is reduced by 7 DPs.
The potioner TP, on the other hand, reads:
Professional Qualifier: A total of 6 ranks in Alchemy and Biochemistry [-3 points]
So it's better to train a little before purchasing this package.
Hope that is what you were looking for.
