Anyone know of any free baby samples?

Looking for free baby samples! I see a lot pop up on facebook but im not sure if theyre real or scams lol i did do the Hello Bello baby diapers and received them a few weeks ago! I didnt realize theyd send a whole box! That was cool! Leave any comments if you know of any! Im due the beginging of October and its always nice to have samples of stuff just to try out
