I did not read all responses but...

I did paid trials for 3 weeks... Cancellations were much higher and the short of it... offering only full price made me more money.

I couldn't even imagine free trials would make you a lick unless you hid that they needed to cancel prior to ending.

not worth it... free trials are a trick...

well i am going to try the whole series, where goes from free for just one day up to a 1 year pass. half year passes area doing great for btw.
