Where can I find baby samples?

I am struggling a bit, as I am recently a single mom, and then was in a wreck, so next check is gonna get hit hard. 😞 I’m due Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. does anyone know any companies that have samples, preferably for baby. I got I think it was the similac or some kind of formula samples in the mail, the Amazon and Babylist baby gift box.
