This is sneaky, but everyone seems to be doing it these days.
They in big letters advertise €1.53 per month, but on checkout you discover they don't offer any monthly payment plans, you can only pay annually, and paying "only" one year upfront the price is 36% higher.
For the price you thought you'd be getting you need to pay 3 years upfront.
Sadly it's everywhere yes. We should be calling companies out on it.
