$50 per month for unlimited, not $50 per friend, so your solution only works if you only have 1 friend, so it would work for me (self-deprecating joke) but may not for GP.

It an outlay of $50 a moth. Probably better to pay 50/number of friends though.

$50 a moth? How about just a lightbulb and an open window?

It took me several re reads to get it.
