Donate and/or volunteer to local food pantries & soup kitchens near you. Some pantries may benefit more from cash donations, it may be best to call and ask what they need/prefer.
If you can't find hygiene products or clothing at your food pantry, try local churches in your area. They usually have "Charity Closets" that you can go to at specific dates during the month.
Where I'm from, most churches have food pantries with clothes & hygiene products, so it may differ depending on where you are. Also, some churches may provide financial assistance.
