Free on a Trial basis

This is just annoying because for this you get a product or service for free but only for a limited time. Two perfect examples of this are in the case of gym memberships where the first month is free with the full payment of a year’s membership or like you can get three free issues of a magazine with a paid subscription.

This is very process as you get with a free sample because the companies giving away the free trial are hoping that once you begin using their product or service, you'll continue to it for a long time.

Sometimes the free trial will be completely free with nothing for you to do once the trial period is over but that is rare. Most of the time you'll be required submit some sort of payment first so that you can try a product and then cancel the membership or subscription once the free trial period is over.

The problem here is that if you don't or forget to, then you'll automatically be billed for the product or service that you really don’t want. A good example of this is the case with the free AOL service for three months. Eventually you will be billed for it even if you don’t like the service simply because you forgot the cut off date.
