any safe websites I can get free trials from?

The Honest Company has free samples but you have to pay shipping and handling.

enfamil and simliac also has free samples

Gerber!

I've heard the honest company is kind of a pain in the butt to cancel though, and if you don't they will take the money out of your card and automatically order a months worth of diapers and wipes etc.

@sgtpeppertheory, it is, they put you on hold forever
