I always object when someone tells me "it's (only) X $ / Y $" and I know for me the relevant part that I want to say out loud is per month, as in, it's a subscription, not a one-time or prepaid amount. I've rid myself of all subscriptions to the degree feasible because whether it's 'little' or 'much' it is recurring, per month so there will likely come a point in the future where I'll just pay without really using that thing anymore or where I forget or can't pay or where I have to pay although that sum could better be spent elsewhere. This is my experience with all subscriptions. I'm even getting my cooking gas as 'prepaid' (i.e. I buy bottles) and I wish I could do the same with electricity and so on.
So I'm totally fine with getting a gift card or whatever you call those thingies in the supermarket where you can throw a lump (20€, 50€) at some provider (Google Play, whatever) and then get to eat up that amount (over the course of at least one year, hopefully). By comparison, I wouldn't sign up even for 1€/month even tho I might get the same for 'less' money—it won't be less, and when you listen to Marie Myers (HP CFO, [1]), corporate knows darn well this is so.
