can anyone point me in the direction of a good place to buy baby stuff?

Gu
Whether it be for the nursery or just general care. I don't have parents, I don't really know any parents that can guide me and help me out, so I'm turning to this app! My husband and I  just found out I'm pregnant after trying since 2015. I'm just trying to get a head start but I didn't really realize the vastness of baby supplies X( please help me! Any and every suggestion is welcome! Thanks !
