I think an alternative that captures the intent might be:Know how you are paying for a service - watch for hidden/ambiguous fees, subscription changes, short-term discounts, sale of personal information - and what you're paying for.

Read every contract and all terms and conditions. While you probably won't understand it all, with practice it will become clearer which are being up-front and which are planning your demise.
