I try to think about subscription costs in multiples of 12, so if I see a $6.99/mo subscription service, I just think "would I pay $84 for this?" and the answer is often no. That's a fairly simple strategy. Obviously, every pricing team wants to lock you into the yearly cost for a long time, so you should really think of it as more like $840.
