I'm culling mine atm, Netflix is gone, BritBox is gone, Prime and Disney+ won't be renewed at the end of current periods. All I've got is NOW sport and entertainment, gonna be canceling Sport in a month, and entertainment probably soon after.
Gonna make a rule of 1 at a time for myself, because there isn't enough I want to watch, and you do end up going through them all not knowing what to actually press play on when you do find things to watch, and I've worked out when I've cancelled them all I'll be saving myself about £60 per month. Which when I put it like that, is a lot of money.
