Free stuff??

I know this is pathetic but does anyone know where to get free baby stuff or really cheap, like free diaper samples, formula and free bottle samples and stuff? I know destination maternity (pea in a pod) gave us a bottle when I shopped their the first time. Target gives you a gift card if you register, stuff like that. I'm having twins and I feel like I'm already going broke lol. Pathetic I know, don't judge lol. 😏
