Why trial periods for a price don't work for me – MEMBERSHIP SITE

An offer that says:
$49 for 3 months trial does not work for me for a simple reason:
I don’t trust that it is easy to cancel the membership.
This is by experience with services purchased before:
It is simply usually hard or difficult to find out how or where to cancel a subscription.
With magazines for instance, I hear people being charged again after saying they wanted to cancel it.
They keep receiving it over and over again!!!
