We'll talk a little bit about free trials below, and we recommend that you take advantage of them if you want to learn more about a tool you're thinking about buying.
But the last thing you want to do is sign up for a free trial that asks for your credit card information. If you do, the company is very likely to charge your credit card after the free trial is over.
If a company has a good name and cares about its customers, it won't ask them for their credit card information for them to use a free trial.
