My grocery bill is steadily climbing and I am not sure what to do. I make too much for SNAP. Any tips or tricks? It's just me in my household, so would buying in bulk be worth it?

Edit: I want to thank everyone for their responses. I have a lot to think about.

We have these amazing little computers in our hands. What are some beneficial things we can do with them? Websites, apps, tinkering... anything you can think of or things you already do. I'm tired of doom scrolling.

I just found out that my neighbor that I share a wall with is moving out because of "the mouse issue." This is the first I've heard about it. I'm pretty sure I don't have mice. I haven't found any chewed food packaging or what looks like mouse droppings. I do have a cat but I'm not confident he would know how to kill a mouse. I've never seen him chase anything on the floor but I know he will chase flying insects. I also haven't been presented with any "presents." Could he really be keeping the mice from my apartment by just his scent?
